Deep Red Coloring

Ingredients

a piece of alum the size of a cherry stone
a gill of soft water in an earthen vessel

Directions

Take twenty grains of cochineal and fifteen grains of cream of tartar finely powdered; add to them a piece of alum the size of a cherry stone and boil them with a gill of soft water in an earthen vessel, slowly, for half an hour. Then strain it through muslin, and keep it tightly corked in a phial. If a little alcohol is added it will keep any length of time.
