Homemade Food Coloring
Why use artificial food coloring when you can make your own? This awesome hands-on activity—perfect for kids and complete with some juicy raspberry smashing to get started on red—comes from our Kitchen Academy box, titled Eat the Rainbow.
For red dye
- 1 cup raspberries (fresh or thawed)
For yellow dye
- 1 cup mangos, cubed
For purple dye
- 1 cup blackberries (fresh or thawed)
For orange dye
- ½ cup mangos, cubed
- ½ cup raspberries
For green dye
- 1 cup frozen spinach (thawed)
Place your ingredient(s) in a blender, or use a mortar and pestle. For red, yellow, and orange dye, smash the ingredients into a pulp or blend until smooth. (Smashing is more fun!) For green dye, use a blender and add 2 tablespoons of water before blending.
Strain the mashed ingredients into a measuring cup through a cheesecloth or fine mesh sieve. If using a cheesecloth, gather the corners to form a ball, then squeeze the juice into the cup. If using a strainer, gently press the fruit (or spinach, for green) with a spoon or spatula.
Transfer the strained liquid to a dropper bottle or small jar. Keep in the refrigerator for up to 2 weeks.
