I would like to buy strawberry ice-cream for my friend, and most of the strawberry-flavored ice-cream is pink in color. However, I am thinking of serving the ice-cream green color instead. Is there any way to color the ice-cream as such? Thank you.

    Green strawberry ice-cream? Is there a story here or do you have a vendetta against someone who you are trying to shock with brain freeze and cognitive dissonance all at once? Commented Mar 20, 2013 at 16:01
  • Pink is light red which combined with green(a mixture of blue and yellow) will create a light brownish color. Very unappetizing.

If you make homemade strawberry ice cream, the color is likely to be very, very pale, approaching white. Green food coloring in your mix should do the trick.

It would be very difficult to retroactively turn commercial ice cream a different color. The pink is almost certainly from food coloring, and mixing in another coloring would be very difficult without adversely affecting the texture of the ice cream--essentially you would end up having to melt and rechurn, to get any kind of decent result, in which case you might as well simply make homemade ice cream.

You can get recipes very easily by googling. You will, of course, need an ice cream maker. The frozeen barrel kind can be had readily and for a reasonable price.

  • depending on the quantity needed, you can use two plastic bags with ice and salt in between them. makes for a tasty chemistry experiment as well.

In a literal sense, rumtscho and SAJ14SAJ are right.

However, if you're willing to be a little adventurous, then you can do this! and without an ice cream machine. And it'll be a fun party trick, to boot.

  • First, buy strawberry ice cream with real strawberries that isn't fully pink (like Haagen Dazs).
  • Second, use pistachio colouring/paste, it's full green and the flavours marry.
  • Third, buy about 3kg (5L or 5 quarts) of liquid nitrogen.
  • Once the ice cream is softer and pliable, put it in a stand mixer (like a KitchenAid robot) and mix in the pistachio mix.
  • The fun part is next, but safety first. Read the entire LN2 primer here (thanks SAJ14SAJ for the recommendation), and follow proper safety protection with liquid nitrogen including skin/face protection and adequate ventilation. Take this seriously and avoid serious harm.

  • Once you've followed the safety precautions, put the mixer on medium speed with the paddle attachment and carefully pour in most of the liquid nitrogen.

  • As the ice cream gets thicker and harder to mix reduce the speed to low. You will reach a beautiful and desired consistency very quickly. You can use the rest of the liquid nitrogen to top-up as your ice cream gets closer to being ready.

It's best served right away, but you can keep it in the freezer for short time. Otherwise it'll lose some of its precious texture.

Here is how light-pink and hot-green will blend. From Color Blender The top and bottom colors mix to give the middle one which is green enough. I think Color Blender uses additive color process, but either way, the Haagen Dazs is light enough in colour to work.

This liquid nitrogen ice cream recipe is from Nathan Myhrvold's Modernist Cuisine.

Can I make this awesome ice cream without a Stand Mixer? Yes. Have a look at this Vivian Macaron entry. Or just google "liquid nitrogen ice cream".

  • While this is probably true and correct, I cannot advise anyone outside a professional or scientific environment to purchase and use liquid nitrogen. There are many safety considerations that must be understood and observed. With regret, given the creativity of this solution (which is the equivilent of remaking the icecream), I have to downvote on safety.

  • Just two safety issues not enumerated here: you should not ride in an enclosed vehicle with the liquid NO2. You should not touch the bowl while making the ice cream, you are likely to injure your hand ("cryoburn") which is very painful.

    @SAJ14SAJ lol, you would. The link provided on safety covers the burns issue you mention as well as the note on adequate ventilation. I feel that enough emphasis and alert has been provided regarding LN2 some of which is the reasonable responsibility of the reader. It is has been deemed safe enough to be referenced in a few cookbooks. Otherwise, for every time you give cooking advice, you should warn people about not touching hot plates and surfaces. Much thanks for bringing more emphasis on the safety here. Now there won't be any confusion.

    @Jefromi Not a killjoy. Though for single use, LN2 is cheaper than the machine. And while we're discussing practicality, I highly recommend buying yourself an ice-cream maker, make 10 batches of ice-cream and if you're still convinced it's more practical than LN2, I'll buy you a tub of ice-cream.

    @MandoMando Burns and other consequences of cooking are well understood by almost everyone. The asphyxiation dangers of LN are not common knowledge. Just two nights ago, I read all of the links regarding LN at cookingissues.com/primers/liquid-nitrogen-primer and there is no way that I would want to take those risks for home use, just for a little ice cream. Most home kitchens certainly, for example, do not turn over air volume six times in an hour. So where is this ice cream to be made?

No, this is not possible for several reasons.

First, you cannot color already-made ice-cream. It is made from frozen crystals of cream, and it is too hard frozen to be mixed with stuff. If you were to drizzle food coloring on it, you'd only get a few dots, but they will not spread through the whole thing. Colored ice cream is made by dissolving food coloring in the liquid cream, then churning it with an ice cream machine into its usual state. The only way for you to add color would be to melt the ice cream first, add the coloring, then freeze it again with a machine. Downsides: you need the machine, else if you just put cream into the freezer, you'd end up with a hard block of milky ice. Also, you would have to start from proper, cream-based ice cream. You can get such in the gelateria. If you just buy a tub of ice cream from the supermarket, it won't work, because it is not made out of milk but from an emulsion which separates into unappetizing phases after melting.

Second, if you want green, starting out with a pink ice cream is a bad idea. You probably had some color theory in school. Pink is made from a small amount of red dye in white ice cream. If you add green dye to the red one, you get brown. You'd have to add very large amounts of green dye before the red hue is lost in the green, and even then, the color won't be too appetizing, it would have a slightly dirty tinge. Also, adding such amounts of food dye to ice cream is not a good idea. First, it can change the taste noticeably. Second, the solvents in the dye can be enough to keep the ice cream for freezing.

Your best option would be to forget the existing pink ice cream, and make your own, adding green dye from the start. For this, you need an ice cream machine (there are inexpensive ones for home use). Then, you have the problem of getting strawberry taste without getting it pink. Homemade ice cream uses real strawberries, and when they are ripe enough to give you a nice flavor, they also color the ice cream. You could try getting synthetic strawberry aroma, but I don't know where you can get a source for it. Alternatively, you could try making low-fat ice cream, starting with a commercially available strawberry-tasting milk drink and mixing it with cream, but again, it will be slightly pink.

If you have an ice cream machine, you can try the homemade route. But it would be much easier if you can go for a different type of unexpected taste/color combination. For example, homemade pineapple ice cream is very pale, almost white. If you color it, say, red, nobody will expect pineapple taste in it. You can go even further and make a very unusual ice cream by infusing the cream with a herb (e.g. rosemary or lemon balm), then color it a hue nobody associates with the taste of herbs.

If you don't have a machine, you could try making something which is not ice cream. For example, you could color a milkshake made using commercial ice cream. You will have no trouble getting the food coloring into the milk. The same problems with mixing colors apply as above - you could make a blue-violet or orange milkshake from a pink ice cream, but a green one would be hard to achieve.

  • The amount of color bleed from mixed in strawberries could be minimized by freezing them before dropping them into the mix...

If you want to start with bought ice cream there isn't really a way to re-color it, but you could coat it in some thing else.

One idea might be dyed white chocolate (just melted and with a small mount of food coloring added). Maybe create small balls of strawberry ice-cream with a watermelon scoop, put on a stick or a tooth pick and dip in the green melted chocolate and put the balls back in the freezer until serving.


I'm going to go ahead and contradict all the existing answers: yes, you can do this. It'd be a lot easier (and better) if you made the ice cream in the first place, but you don't have to.

As others have said, start with as white as possible a strawberry ice cream, so that your green food coloring doesn't have much to cover up.

Dump the whole thing in a stand mixer, and use the paddle attachment to stir it until it softens up enough to add in some food coloring and get it mixed in. The coloring may not be completely smooth, but it should mix in well - this method also works for mixing in liquid flavorings (like liqueurs) and solid mix-ins (cookie bits, nuts, and so on). It will hurt the texture a bit, but as long as you don't let it soften too much, it'll be fine.

If you don't have a stand mixer, you can do the same thing by hand, but it'll be tougher - either you'll have to work really hard to do what the stand mixer would, or you'll let it get softer in order to mix it, and end up compromising the texture more.

And lest people say this won't work: even David Lebovitz suggests it, in the mix-ins section of The Perfect Scoop. Sure, food coloring may end up a bit swirly, but it's better than nothing! It works because storebought ice cream is made to be really soft before it melts (easier to scoop and more fun to eat) so bringing it to where it's just soft enough to mix doesn't damage the structure as much as it would with homemade ice cream.

  • This will surely work, but if you refreeze it rather than serving immediately, you will get larger ice crystals than were in the ice cream originally. In my opinion, that is a deleterious effect on the texture and mouth feel (it will feel grittier or grainy), but you would have to decide how much that matters to you.

  • @SAJ14SAJ I think it's not as bad as you'd imagine, particularly if you're good about only mixing as much as necessary and not letting it warm up too much. The mixer is essentially churning it (though not quite as well as an ice cream maker), and so if it doesn't actually melt, it'll be mostly okay.

Why not just buy Pistachio ice cream and add your own strawberries? You can slice & dice them and let the IC soften ever so little and mix them in and refreeze. However you always run the risk of getting the icky crystals that can form on refrozen ice cream. Better yet add the strawberries when you are serving it.

BTW, there is an ice cream maker attachment for the kitchen aid mixer. :)
