A quart of rich milk, three-quarters of a pound of sugar, five ounces of
coffee, eight egg yolks. Grind the coffee and stir it into half a pint
of boiling milk, set it one side; put the rest of the milk in a double
boiler, beat the eggs and sugar together until light, stir into the hot
milk, stir briskly until it thickens, add the milk and coffee, turn it
into a bowl and let it stand until the last moment; strain and freeze.
