Whip a pint of cream very stiff; turn it onto a sieve to drain for a few minutes so it will be entirely dry. Return it to the bowl and whip into it lightly four tablespoonfuls of powdered sugar and a tablespoonful of curacao, of noyau, of kirsch, or of very black coffee, or a teaspoonful of any flavoring extract, or an ounce of chocolate, melted, and diluted with a little milk or cream, and flavor with a few drops of vanilla. When a liqueur is used for flavoring less sugar is needed than with coffee, chocolate, or essences. Turn the cream into a mold and pack it in ice and salt for four hours. Garnish the dish with small iced cakes.
