Allow 1 bar of Allinson's chocolate for each cup of fluid. Break the chocolate in bits, put into a saucepan, add a little boiling water, put on the fire, and stir until the chocolate is dissolved, then add rest of fluid and boil 2 or 3 minutes. Pour the chocolate into cups, and add about 1 tablespoonful of fresh milk to each cup, but no extra sugar. The milk may be added to the chocolate whilst boiling, if desired.
