Food coloring can enhance your perception of taste, any kid i’m sure will agree with that. The bad news is that many food colorings approved by the U.S. contain toxic substance and are actually banned in other countries. The good news is that you can easily color your foods with items in your pantry. All recipes here are based on coloring about 1 cup of white cake icing. To color other items, experiment with amounts of natural dyes until you achieve the color you want.
7 Don't forget to taste your food as you color it. Since these natural dyes are also foods in their own right, adding too much can impart their flavor into the icing. You will need to find the right balance between color and neutral flavor.
Mash half a small avocado until creamy paste to get pastel green. Mix this into your icing. The avocado makes your icing thinner, but in a fluffy, pleasant way.
