Quantity for about six custard glasses. Take 6 oz. of good chocolate, not less than 2s. per lb. Dissolve it in hot water in a clean copper over the fire - just enough water to melt it to a paste. Add a teacupful of milk, and let it boil up. Pour the mixture on to five yolks of eggs beaten up, and put it all on the fire again, stirring it till it just boils. Take off quickly and leave it to cool, or in summer stand it on ice.
