Six tablespoonfuls of cocoa to each pint of water, as much milk as water, sugar to taste. Rub cocoa smooth in a little cold water; have ready on the fire a pint of boiling water; stir in grated cocoa paste. Boil twenty minutes, add milk and boil five minutes more, stirring often. Sweeten in cups so as to suit different tastes.
