Homemade Food Coloring: How to Make Natural Food Dyes

How to Make Natural Food Dyes |

So, I’ve written a fair bit here at Nourishing Joy about natural food dyes.

However, the first post I put up on the subject was Naturally Dyed Easter Eggs, which is a very helpful post if you’re making Easter eggs, but as time has gone on, I’ve realized the post hasn’t been all that helpful for other food-related uses, such as buttercream and play dough.

So, I’ve decided it’s high-time to give homemade natural food dyes their rightful place in a post all their own.

{It’s about time, don’t you think?}

Especially since conventional food dyes are petroleum based and are linked to such things as hyperactivity in children, increased food sensitivities, and even rashes and eczema, it’s more and more important to know how to make your own homemade food coloring. (I wrote a whoooooole lot about that in my post about The Fake Food You Don’t Know You’re Eating.) Who wants to deal with that? Natural is definitely the way to go on this one!

So, without further ado, I give you homemade, natural food coloring!


Natural Food Dyes


Three things to keep in mind:

1. Natural colorants often lend a more demure hue than their petroleum-laden cousins. This is merely due to ratios : a concentrated store-bought food coloring requires only a few drops to add color and thus doesn’t change the texture of the food by adding vast amounts of liquid. By comparison, it’s difficult to get a true “red” from beet juice rather than just pink, not because the beet juice isn’t red enough, but because most recipes can’t stand up to the amount of liquid required to obtain a true red.

On the other hand, just a few drops of beet juice will create an absolutely lovely pink in frostings and ice creams without adding even a hint of beet flavor. (See the list below for a number of gorgeous examples….)

2. Since these colorants are foods themselves, remember that strongly colored foods also tend to be strongly flavored foods, so try – as much as possible – to avoid using large quantities of any of these (a small amount of cinnamon, for example, might make a frosting heavenly, but a large amount would render it inedible).

Also keep your final flavor in mind so that the colorants don’t overwhelm it. I’m assuming you don’t necessarily want paprika spiked buttercream or parsley ice cream! Again, small amounts of those colorants won’t even be noticeable, but large amounts most certainly will.

3. Lastly, vegetable powders are great ways to add vivid colors without adding excess liquid, so if you’re wanting a deep red, for example, use beet powder rather than beet juice. Another alternative is to reduce your liquid to a concentrated syrup, so see even farther below for a two quick tutorials on how to make vegetable powders and how to make concentrated homemade food coloring, just like you’d buy in a store.

Making your own homemade food coloring is easier than you think!

These dyes are displayed in a standard American buttercream.



Natural Food Dyes / Homemade Food Coloring

Start with a small pinch or a few drops of these colorants and add more according to your desired shade.


  • pure beet juice
  • beet powder
  • pure pomegranate juice


  • pure beet juice
  • pure cranberry juice
  • pure raspberry juice


  • pure carrot juice
  • carrot powder
  • paprika


  • fresh turmeric juice
  • ground turmeric
  • saffron



(FYI: Blues and purples are notorious for being the most difficult dyes to produce, either naturally or in a lab!)

  • red cabbage juice
  • stir a bit of baking soda in with red cabbage juice or a purple dye for a brighter blue


  • purple sweet potatoes
  • pure blueberry juice
  • purple grape juice, concentrated



  • cocoa powder
  • pure espresso
  • instant coffee granules
  • heavily steeped black tea
  • cinnamon


And of course, if you can’t get the color you want from making your own homemade natural food dyes, you can always buy a vegetable-based food coloring, but they’re pricey: See Vegetable-based food coloring.

The SECRET to Successful Homemade Food Coloring

This is more common sense than secret, but it still took me several years of tinkering to realize what makes a great natural food coloring – and that is:

The best homemade food colorings are intense in both color AND opacity.

Again, this may seem oversimplified, but consider this: if you take pure pomegranate juice and look at it, it looks rather intense, doesn’t it? It’s a deep red! But then pour some in a clear glass and hold it up to the light. Even though it’s bright and intense, it’s also opaque. You can sort of see through it. Now do the same thing with freshly juiced beet juice. It’s intense too, but when you hold it up to the light, it’s absolutely dark. You can’t see through it at all.

THAT’s the mark of a good food dye. And if even those intense dyes aren’t intense enough – say, you’re wanting to make a fire-engine cake or Cookie Monster cupcakes for your child’s birthday – then that’s when you need to concentrate that dye even further so you can use A LOT of it without changing the texture or the flavor of the frosting.

(Word to the wise: that’s nearly impossible to do with blue and still have it taste edible, so Cookie Monster cupcakes will be difficult. You have been warned. :) )

Thus, the most successful natural food colorings are:

  • powders made from deep colored vegetables
  • fresh juice from intensely colored fruits, vegetables, or herbs
  • concentrated syrups from fresh fruit or vegetable juices


How to Make Vegetable Powders for Homemade Food Coloring

To make any herb or vegetable powder called for here, slice the desired vegetable paper thin (or merely place whole herbs or berries on a tray) and dehydrate in a food dehydrator or oven set at about 150° until fully, absolutely, completely dry (2-6 hours, depending on the vegetable).

Place dried vegetable/fruit chips or herbs in a coffee grinder or blender and grind until you have a fine powder.

Store in an airtight container for up to 1 year.


How to Make Concentrated Liquid Homemade Food Coloring

Another option for making a more concentrated dye is to reduce a deeply colored liquid, such as beet juice or the juice from purple sweet potatoes, into a syrup. This will allow you to make more vivid colors without affecting the flavor or texture quite as much.

To make a concentrate, place about 1 cup of freshly squeezed juice over very low heat. The only way I’ve been able to do this successfully is with a mini-crockpot. I use this one.

Leave the lid off the pot so the liquid can evaporate and heat until the juice begins to thicken and drips slowly off a spoon rather than running off easily, about 24 hours, give or take 8 hours depending on your climate and pot. The liquid will be less than 1/4 of its original volume.

Use this concentrated liquid as your colorant directly OR mix it with a bit of glycerin in a 2:1 ratio (colorant:glycerin) and store in the refrigerator for 2-4 weeks.

UPDATE: Using natural dyes as natural fabric dyes

In the comments, several people have wondered about using these natural food dyes for dyeing fabric. I am woefully ignorant in this regard, but I just ran across a post that might be helpful: Condo Blues: How to Dye a Shirt Minion Yellow with Turmeric.

This woman dyed a white t-shirt bright yellow using ground tumeric and gives detailed instructions and notes. So, perhaps the same process would work with beet juice or other natural dyes? I don’t know – has anyone else tried it? Does the dye stay once it’s been set?


Have I missed any great dyes or homemade food coloring options? How do you like to use homemade natural food coloring? Let us know below!

  1. Lyz Foster says

    Love this!!! I have been looking for ways to naturally color my soaps and thanks to you I have a whole new arsenal to work with, not sure why I didn’t think of it, but thank you :))

    • Kresha says

      You’re welcome! I’ve only used micas in my soaps, so now you’ve given a good idea too! I’ve seen activated charcoal in soap before – I would how beet powder would do? ;-)

      Good luck and have fun!

      • Lyz says

        Oh I can’t wait to try the beet powder, can’t imagine the colors!!! The tumeric so far is my favorite, a nice coppery color.

    • Kathee says

      I use natural colorants in my soaps too. Soooo many of them have phenomenal topical benefits. Spirulina (the Holy grail), Nettle Leaf, & Slippery Elm Bark (all powders) are some of my favorites – AND they don’t shorten the shelf life. Thanks for the info on Beet Root. I’ve got an idea for a PMS/Menopause soap & have been wondering how I would color. Now I know! Thanks so much!

  2. Tracy Spangler says

    Thanks so much for posting this! It came at the perfect time! I’m trying to see what plant based dyes will work best with chapstick, and crayons!

    • Kresha says

      Fabulous! I’d love to hear your results! I suspect that you’ll need to use dry powders, as my attempts at crayons with liquid natural colorants were a major fail. ;-)

    • Wendy says

      I’ve been wanting to try natural colorants in my lip balm recipes as well. Which do you think will work better, powders or liquid

      • Kresha says

        Hmmm… well, if you’re only going to use a few drops, a concentrated liquid, like beet juice, might work just fine, but if it’s more than a few drops, you’ll likely offset the chemistry that’s happening between the oils and it would either soften them too much, keep them from setting, or seep out if the lip balm was ever set in a warm place.

        Thus, powders would likely be more stable and more potent, but I don’t know at what point they would make the lip balm go from smooth and satiny to grainy. I suspect mica powders are used in commercial brands, so I’m sure it’s possible.

        Was that helpful? Or clear as mud? :-)

        • Wendy says

          Thank you for you input. I don’t know why I didn’t think of this before, but I’ve used cocoa powder before without it getting grainy so I suspect beet powder may work as well. I will try a small batch.

          • Kristen F. says

            I have tried everything to naturally color my home made lip balm and nothing works. Beet root powder is like adding sand, and beet juice does not mix in with the fats and beeswax. I even tried to use organic glycerine and seeped beets and beet powder in it and that didn’t work either. If anyone knows a sure fire was to naturally color lip balm please let me know…thanks!

          • Kresha Faber says


            I’ll put this in my notes to research.

            In the meantime, I know the store-bought “natural” lip balms often list mica as the colorant. Is that an ingredient you’d be willing to use or would you prefer to stay with various food-based colorants?

  3. Kerri Mayo says

    I’m going to experiment with beet powder. My son wants a fireman birthday cake. Can’t wait to try it! Thank you!

    • Maria says

      Kerri, just curious about how the fireman cake turned out. I’m looking to make a superhero cake for my daughter and I was also thinking about using beet powder. Hope you can let me know. Thanks :)

  4. Katrina says

    I appreciate this – lots more ideas for dyeing cottons a variety of colors. Is there a preferred way to use these for cottons? :D

    • Kresha says

      I have NO idea but I’m definitely intrigued! :-) I’m sorry I can’t be of more help.

      I’ve never tried these on fabrics, so DEFINITELY do a test run and see how much the colors bleed in the wash before doing large scale projects. And then please let us know how it goes – like I said, my interest is very piqued!

      • Katrina says

        Thank you, Kresha. This is a future project but will come back with results. I hae used different teas to dye cotton for an aged effect so am looking forward to experimenting with this. :)

        • Lyz says

          Ok this took some time, but according to my sources, food dyes weren’t really used for clothing, simply because there was no way to “set” in the colors, they used them for rugs and such, things that weren’t washed all the time or never, as the color would bleed out. I know this isn’t helpful, but I’m thinking with a little web searching you may be able to find a way to set the colors.

          • Laura B says

            Dharma Trading company not only sells natural fabric dyes and mordants (the stuff that sets the dye in fabric) but they have tons of information on their web site as well as a very knowledgable staff–if you call.
            For me, I found you looking for natural food coloring. We (finaly discovered) that our kids are VERY sensitive to artificial colors. They might as well use meth as have a cupcake with red frosting–or one of the millions of things that have color (especially red #40). About 15 minutes after ingesting food that is artificially colored they start to act wild, completely out of control. Since we have given it up entirely at our house I am always looking for ways to provide healty treats that don’t make them feel like they are missing out, especially around the holidays. Thank you so much for the tip about using veggie powders. We have been buying the very expensive natural food coloring to do our christmas cokies but this year we have something new to try!!! Thank you!!!

    • Lyz says

      I live in NM, home of the Navajo Nation, master crafters of all I swear. They use natural dyes for their wools to make their blankets and so forth. I will see if I can ask around as to what is best for “setting” the color. I know just the person to start with too :)

      • Kresha says

        Oh, that’s wonderful! Yes, you are so right – the Navajo are amazing weavers and crafters. I will definitely look forward to hearing about what you hear!!! Thank you so much.

      • Claire says

        I am also curious about dying fabrics – I have been eating beets a lot lately and I boil them. The remaining water is a beautiful color.

  5. Laurie says

    I love your ideas! HOWEVER……the natural vegetable based colorings you link to as a recommendation (India Tree) uses Sodium hydroxide as an additive in their yellow coloring! This Is a poisonous ingredient! Paste this link into your browser and see……….
    We all need to be diligent and read every ingredient, even though a product advertises itself as natural. I will, however, use the ingredients you suggested……

    • Kresha says

      Yes, I have sodium hydroxide in my cupboard to make soap. It is indeed toxic. :-)

      However, I’m curious why you say the India Tree colors have sodium hydroxide, as on India Tree’s own website, they state that the only ingredients in their yellow dye are deionized water, glycerin, and turmeric:

      Perhaps it’s different in different countries???? I don’t know where you are, but perhaps they have different formulations, or have changed their formulation?

      Thank you, though, for the always-needed reminder to check every ingredient, even on products that claim to be “natural.” :-)

      • Toute Swite says

        As my dermatologist says about “natural” products – “Poison Ivy is natural, but would you want it on your skin?” Good discussion, though. Many thanks to you all for some great ideas.

      • Kathee says

        BTDubbs – sodium hydroxide (lye) IS a natural product. Still toxic- but a natural product! And cooks out when making soap, so maybe it neutralizes other ways too. That would be neat to know- has anybody worked with it other than in soaps (& unclogging drains)?

    • teresa says

      actually, lye is a natural ingredient, it is achieved by dripping water (rain water is best-no chemical additives) through wood ash. the liquid is then boiled til a chicken feather melts when placed in the liquid.
      it was used to make soaps for centuries. yes, it is dangerous and caustic and should be used with precautions but i don’t view it as NOT natural.

      • teresa says

        oops, my computer posted before i was done.
        lye or soduim hydroxide is normally neutralized by the heating (either in cold process soap making or hot process soap making) and therefore not harmfull.
        if someone is putting it into food or body products, there is a different issue going on because it will burn like mad on the skin (ask me how i know.)
        the only way to neutralize lye without cooking is using vinegar (yes, it give instant relief on the back of hand or finger that touched it.)

    • Carol says

      Apparently, they went back to the older, original recipe which does NOT contain the harmful chemicals like anti-freze. They USED to but now don’t…unless you got an older package before they went back to the glycerine/food/water recipe.

      I’m looking for colorings for playdough. I did buy the ‘natural’ food dye from Amazon, but want to try making my own first…
      I’m also thinking about drying some organic blueberries to put in my homemade mascara to give a blue/purple tint.

  6. Michelle says

    Hi I’m going to attempt to make my sons first birthday cake and want to make it blue, could I make a blueberry powder? Would that work?

    • Kresha Faber says

      How fun!

      And yes, I would think a blueberry powder might work very well, but it will take a few days to dehydrate, as they’re pretty juicy. :) Also, how blue are you wanting it? Like Cookie Monster blue or a light pastel blue? If you’re wanting a deeper blue, I would definitely choose a cake that tastes good with blueberry, as if you’re wanting a deep blue, the flavor will definitely come through.

      I hope that helps!

      • Wendi says

        Hi Kresha,

        I came across your site looking for ideas for natural food colorings. As far as blueberries go, since the berry itself is not blue (sort of brownish/yellowish) couldn’t you pop the berry out of the skin, enjoy the berry (as in eating it), and dry the skins to pulverize?

        I think that would also mitigate the flavoring you would get from the coloring. I may not have a clue what I am talking about since I have not tried to make food colorings, but I do eat blueberries. :)

        • Kresha Faber says

          I haven’t tried it, but that sounds like a fantastic idea! It might take awhile to pop all the berries out, but it would shorten the drying time considerably for sure.

          Thanks for a great tip! (And if anyone tries this before I get a chance to, please let us know how it goes! :-) )

    • Kim says

      to make a blue colour boil red cabbage between 10 – 30 minutes strain the liquid the add less than 1/2 teaspoon bicarb soda (baking soda). the bicarb changes the ph which changes the liquid from purple to blue

    • Kresha Faber says

      I haven’t, but I know Robin over at has done a lot with homemade natural make-ups, so perhaps ask there too! :-)

  7. Cassandra says

    I am considering using this in homemade hand soap. If I use beet juice do you think that will stain hands add they use the soap? Thank you.

    • Kresha Faber says

      Hmmm… I think if you use just a small amount, it wouldn’t be noticeable, but for any really defined pink, it might! I haven’t tried it, so I can’t say, but would it be possible to add just to one bar to try? Or do you use a block mold for your bars? If it’s liquid soap, could you try it in just a small amount?

      (And if you do, please let us know how it worked! I know others are wondering the same thing!)

  8. Kelcey says

    I wanted a natural food coloring for some frosting for Valentines Day. I didn’t have time to drive all the way in to my Whole Foods store, so I googled natural food colorings and found your site. When I read about the beet powder I remembered that I had a beet powder supplement in capsules. I just opened a few of them and added it to the frosting to the desired color. They worked beautifully with no discernible taste. Thanks for the great idea!

  9. Shannon says

    Thank you so much., we recently found out my son is allergic to artificial food dyes (maybe flavor too) and it’s so hard to see everyone enjoy colorful cookies except him:( this will definitely make him a happier 7 year old!!

  10. says

    Good Morning :-) Thank you so much for this very informative post! I have begun making my own dyes as well so that my children can enjoy the brightly colored treats! I am the blog author of Three Kids And A Fish and I am writing a post today on natural food coloring, and I wanted to let you know that I mention this post as a great place to go to know what to use to make your own natural food coloring! Again, thank you very much!

  11. Julie says

    I own a juice bar so it seems to me you could run the vegetable through a juicier and then dehydratethe pulp and then grind it up….just a thought….

  12. P.J. says

    I want to create some black (or at least pretty black) wooden kitchen and serving pieces: cutting boards, a salad bowl… (and a challah board), and I can’t find a wood dark enough. Do you think the charcoal powder would work and be food safe on wood? How would you apply it? Thanks!

    • Kresha Faber says

      Oh, goodness. That’s a great idea and unfortunately I don’t have any expertise in this! If you use activated charcoal, it should be fine, food-safe-wise, but I don’t have any ideas on how to actually stain the wood. Perhaps rub charcoal and olive oil alternatively into the wood in several coats, like you do when you’re oiling a new cutting board? I have no idea if that would actually work? But honestly, I think that would give a shadow to the wood, but wouldn’t actually give a lovely deep dark stain to it.

      Do any other readers have any ideas?

      Thanks for a great question!

      • Willis says

        Fantastic article! Thanks for sharing!

        I would think squid ink would make an excellent dye for wood utensils and boards. Certainly food-safe, and I would think pretty effective.

        Would love to hear about the results if you decide to try it P.J.

  13. says

    You can also take dried hibiscus flowers and crush them with a mortar and pestle, or make a powder in a food processor. This gives a pink hue when added to dishes. The hibiscus I buy is a loose-leaf tea. It tends to add a sour strawberry-like taste to foods.
    Annatto can also be used to color foods yellow. From my experience, it needs fat to bring out the color. Like adding butter to cake batter. I tried dye-ing soup with it, but it would not dye the liquid, only the fat floating on top. Used the pure seeds in a tea-infuser, maybe it would be different crushed?

  14. Kerri says

    This is great…I try to reduce artificial dyes from my sons diet…but eliminated red40 altogether…but don’t want him feeling left out when decorating cookies or cakes…does the charcoal powder or squid ink have a strange taste at all?

    • Kresha Faber says

      It depends on how much you use and in what application. For example, are you just making typical chocolate cupcakes or are you making a soccer ball cake where you want half the frosting very black? Those two may require different amounts of dye.

      For black frosting, I would actually tint the frosting green first to get it dark, along with a strong flavor such as vanilla, then add the charcoal or squid ink. (I suspect squid ink may vary by brand as well. The one linked to above is the only brand I’ve used and it’s rather mild – you have to use a fair bit before you actually taste or smell anything but the frosting.) As for the charcoal, it should be ground very very fine, like cocoa powder, if you’re going to use it in something silky and soft like frosting. A mortar and pestle or a coffee grinder work well for this.

      This also would be an excellent application in which to use chocolate. That way you can get the frosting quite dark and quite strongly flavored before you even add the charcoal or the squid ink, so you don’t need as much.

      So, good luck and I hope that helps!

  15. Jen says

    Wow! I was so excited when I found this. My 11 year old was been baking and we have had a lot of fun experimenting. I can’t believe the beauty of the colors!!! They are better than artificial. The carrot juice made a beautiful yellow as well as orange. The beet juice was beautiful. It was fun to experiment with different shades. After juicing them, I put the leftovers in ice cube trays and froze them and we used them again! Have you tried Or have any suggestions about coloring candy(white chocolate)? Maybe powders because I don’t think it is suppose to get “wet”.

    • Kresha Faber says

      Yay! And what a great idea to freeze the leftovers! I’m going to have to do that the next time I juice…. ;-)

      I haven’t tried coloring white chocolate, but my instinct is the same as yours – to use a very fine powder with the melted chocolate. Any liquid could definitely make the chocolate seize and turn grainy.

      Thanks for a great comment!

  16. Annabelle says

    I was thinking of making my own Tempera paint with natural colouring. Do you think these recipes would work for paints? Thank you

    • Kresha Faber says

      Hmm…. that’s a great question! I would think if you use powders or very concentrated liquids (by reducing them on a simmer on the stove) and then mixing them in your egg yolks, that could work very well. There’s a great link about this over on our How to Make Crayons post, because during my first foray into making crayons we tried every natural colorant in the book. ;-)

  17. lisa says

    i would love to know if you have tried any of these in either melt and pour soap or cp and how it turned out.

    • Kresha Faber says

      I have not tried them in melt and pour soaps, but I’ve tried beet powder and activated charcoal in cold process soap and they worked wonderfully. I haven’t tried any juices or liquids in cold process soaps, but I suspect the chemical reaction might change the color. (Like when I used them in crayons….) But again, I haven’t tried it, so who knows. ;)

  18. says

    Excellent for natural cool rants. Not checked out the rest of the site yet but this was the reason I was researching today. My children like red velvet. I tried it with the beet root but found it too wet, too much beet root, probably. My main man would like a football (something to do with soccer, that is) cake so I am thinking of either a football pitch or a team shirt so reds, yellows and green are perfect.

    Let you know how it turns out.

    Well done Kresha

  19. Domonique McDaniel says

    Hi you talking about food coloring because I’m going to do it with my mom today. I like food coloring .

  20. Dave says

    Hi! Thanks for the article, it’s very informative. I going to stain some untreated new wood and was curious how much of the stain would oxidize over time, like the purple in the beets turning brownish. And if this happens only with fresh beat juice as apposed to beet powder.

    Any experience with this?

    Thank you!

    • Kresha Faber says

      Ai! I have no idea. It’s a GREAT question, but I have no experience with this. Anyone else care to chime in or point us in the right direction?

  21. lydia says

    I love this article and all of the comments. Thanks for posting. I’m interested in using spinach juice to color my bath bombs. But I’m worried about it spoiling. I left the juice out for 3 days and it started smelling funky. How can I preserve the juice in the bath bomb so it can be stored for a long period of time? I’ve been wracking my brain thinking of ways to do this but haven’t come up with a good solution. Hoping you can help. :)

    • Kresha Faber says

      Hmmm… Well, do you use citric acid in your bath bombs? That would certainly act as a preservative, as would salt. However, I have no idea HOW long the shelf life would be. Anyone else have any experience with this?

      Sounds like a great project for St. Patrick’s Day, too! Oh, the possibilities…. :)

  22. Joan Haris says

    After introducing fresh beets at dinner to Grandchildren tonight and having them actually eat some we got into discussion of using red beet juice for dying.. Can one dye some simple tee shirts as a project for them and get a fairly bright color?. Their enthusiasm is high about such a project and I want to take advantage of it. Would putting beets in a blender with water get to the consistency where I could achieve a bright color?. I really want to seize the moment and get them involved in creating something for them to show off to their friends..

    • Kresha Faber says

      That would be SO cool!

      Let’s see – I haven’t tried dying fabric with beet juice, but after seeing the turmeric dying tutorial linked above, I have high hopes. If so, I don’t think blending raw beets with water would be potent enough – I think you’d need to juice them so that you have 100% beet juice as your dye.

      But again, I haven’t tried it, so perhaps someone else who has had more experience with dying with natural dyes could chime in?

      Good luck and HAVE FUN! :)

  23. G.Siva Avinash says

    the information you have given is so good.i loved this.
    how can i make cabbage 65 into a blue colour one

  24. Katherine says

    I want to color epsom salts bright red for Christmas to use in homemade bath salts. Was thinking beet powder and then add a little water to it, then toss with the salt??

    • Kresha Faber says

      Hmmm…. I’m not sure whether the red of the beets will transfer to the salt or not. I haven’t tried it. Definitely try it before you give them as gifts. :) Also, I suspect pure beet juice would work better than reconstituted beet powder – if you don’t have a juicer, you can blend raw beets with a few teaspoons of water (just enough to get it moving in the blender), then strain the liquid through a cheesecloth.

      Good luck!

  25. Heather says

    Really great ideas here, thank you everyone for sharing! My most successful natural color is using chlorophyll for green (looks amazing). I am however having a lot of trouble with blue. I was able to find the sweet spot for how much baking soda to add to my boiled cabbage juice to create a nice blue hue and flavor. My problem is that once I add the coloring (which has to be very quickly or it starts turning Aqua marine and then green…) to the product, the color is nothing more than a subtle grey. Very unappetizing and definitely not blue as requested by 4yr old.
    Any suggestions as to what I may be doing wrong?! Thank you :)

      You’re not doing anything wrong! Blue is SO HARD to make. I even once bought a box of natural food coloring from the store and the blue did EXACTLY what you described.

      The only thing I can suggest is perhaps start with a deeper purple, like purple sweet potato (which, unfortunately, is difficult to find outside of large urban areas) and use it either alone or with a bit of baking soda. Other than that, blues are so so difficult!

      Ooooo!!! Thanks for the great tip! I’ll hunt some down and then update the post. :)

      So, you recommend using JUST the peels, not the black cherry juice itself? In that case, do you tend to grind them, macerate them, dry them, or do something else to add them to your various foods (like frosting)?

      Can’t wait to try it! I love black cherries…….. :)

    What is the shelf life for these food dyes, specifically the blue dye made with red cabbage and baking soda? I’m wondering how far in advance I can make the blue dye for cake icing.

    • Kresha Faber says

      If you’re making the concentrated version of these dyes with glycerin, they typically keep for at least two weeks in the refrigerator, although – admittedly – the blue dye is the most volatile, so using it as fresh as possible is the best option. (By the way, if you’re going to make a concentrated blue dye, I would reduce the cabbage juice and THEN add the baking soda, rather than adding the baking soda before reducing.)

      If you’re making the dye fresh and are not concentrating it, I would make it with 24 hours of use. I find the blue discolors faster than the other ones, so the fresher, the better.

      I hope that helps! :)

    So glad I came across the article today! I came across chalkboard cakes this morning in my newsfeed and was thinking I should be able to do that all natural..Black Cocoa royal icing yes! I have this very expensive bag I never use for anything and now I can use it to make black icing. for the chalkboard cookies! Woot Woot!

    Thank you for all the wonderful information about natural food coloring! I am wondering if using homemade food colors in royal icing would change the shelf-life of the finished product? Since the natural food coloring has a much shorter shelf-life than artificial coloring, would that extend into the finished product as well – once the royal icing has hardened?

    • Kresha Faber says

      No, once the royal icing has hardened it shouldn’t be an issue.

      There are two reasons homemade food colorings have shorter shelf lives:

      1. The color changes as it sits or is exposed to light.

      2. Molds can grow on them since they’re not preserved (using glycerin as described above helps avoid this).

      However, once royal icing has hardened, the moisture has pretty much evaporated, so molds are no longer an issue, and the colors are fairly well set, so again, that’s not much of an issue. I might be inclined to make your icings a bit darker or brighter than you’d like the finished colors to be, as they might fade a bit as they sit over time, but the color issue in a fixed, hardened icing isn’t nearly as dramatic as it can be as food dyes sit by themselves.

      I hope that helps!
