Lê techniquê- How to make natural food coloring

I pride myself on saying that I don't use synthetic food colorings in my cooking but this was a problem I've always had since I started my career in the pastry field. It's very hard to stay away from food coloring simply because the pastries are colored.
There are evidences showing that synthetic food dyes can cause organ damages, can trigger hyperactivity and even worst diseases but still it's approved for human consumption.  We don't have to be experts to know that anything synthetic is not healthy and the fact that  who suffers the most are the kids since all colored foods are marketed to kids it upsets me.  Since I've always refused to use it I had to come up with different techniques to achieve colors aside from the synthetic gross liquid sold out there.

There is nothing wrong with the colors itself, they are beautiful and my whole world spins around it but we gotta make it right and here I'm going to teach you how to make it right.

If you use the correct fruits and veggies to color your food, it will work perfectly in your recipes and it won't reflect any taste from these ingredients used. The biggest trick is to achieve blue since there is no fruit with such color (at least here in the States). Blueberries may be the first option that comes to your mind but they are actually purple when you crush them so they are not helpful for this matter.
In order to make blue you have to create a chemical reaction with red cabbage and baking soda. Since Red cabbage juice is a Ph indicator it will react with ingredients of different phs such as baking soda. Baking soda neutralizes acids and brings a color change to the cabbage juice and just like magic you will end up with an incredible shade of blue that can be applied to your food safely.

Overall it's possible to extract the juices from fruits and veggies in a blender or food processor so don't worry if you don't have a juicer, I'll give you different options in this video and guide you thought.
You will learn how to make red, yellow, blue,orange, purple and green.

I hope this episode of Lê technique inspire you to make your food  colored but for real using only other food ingredients.

Let the revolution begin!


  1. Hello,
    Can you use the raspberry red coloring for red velvet cake and will it alter the taste?

    1. Hello Awa, you can absolutely do that but you should use the "concentrated" technique. The original red velvet cake was made with beets which is more cost effective because you will need a lot. Just cook them in water like I did with the cabbage and then reduce the liquids to make it more concentrated. It will look gorgeous but keep in mind that natural food colors are a bit less bright then artificial ones ;) ps: let me know how it turns out.

  2. Thank you for sharing the food coloring from the good stuff for the body. I'm really impressed with them and will perform in recent times.
