To Color Ice Cream or Water-ices

Ingredients

Directions

  1. For green, use juice of spinach or beet leaves.

  2. For yellow, use saffron soaked in warm water.

  3. For red, pound 1 ounce of cochineal and add ½ pint of boiling water, 1½ ounces of cream of tartar, ¼ ounce of alum, and ⅛ ounce of salt of tartar.

  4. Let the mixture stand until the color is extracted, then strain and bottle.

  5. For purple, mix a small quantity of cochineal and ultramarine blue.

  6. For brown, use powdered chocolate.
