Red Food Dye
How to make naturally colored frosting using plants--no synthetic dyes!
Rinse, trim, and chop beets. Place pieces in a blender or food processor and grind to a pulp.
Combine pulp and water in a saucepan and bring to a simmer. Continue to simmer for about 40 minutes, stirring occasionally.
Set a strainer over a bowl. Pour mixture through strainer, pressing ground beets against the strainer to squeeze out all extra liquid.
Use the liquid as a replacement for the water or milk in your frosting recipe.
