As anyone with kids can tell you, food coloring can enhance your perception of taste. 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.
Add 1 tsp of stale turmeric for yellow. Turmeric is often used to give vegan puddings and tofu scrambles that "eggy" shade. This is a good use for turmeric that's past its prime, since stale turmeric is fairly flavor neutral.
Mash the juice from 14 fresh or thawed frozen raspberries directly into the icing using a sieve to create blush or pale pink
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.
Mash the juice from 14 fresh or thawed frozen blueberries and 12 fresh or thawed frozen blackberries directly into the icing for raspberry purple, using a sieve.
Experiment and color your world! Other natural sources of color include carrots, beet juice and chlorella.
