One quart of sweet cream, the yolks of four eggs beaten together with a cupful of sugar. Dissolve half an ounce of gelatine or isinglass in half a teacupful of warm water; when it is dissolved stir in a pint of boiling hot cream; add the beaten yolks and sugar; cook all together until it begins to thicken, then remove from the fire and add the other pint of cold cream whipped to a stiff froth, adding a little at a time and beating hard. Season with vanilla or lemon. Whip the whites of the eggs for the top. Dip the mold in cold water before filling; set it in a cold place. To this could be added almonds, pounded, grated chocolate, peaches, pineapples, strawberries, raspberries, or any seasonable fruit.
Pick off the hulls of a box of strawberries, bruise them in a basin with a cup of powered sugar; rub this through a sieve and mix with it a pint of whipped cream and one ounce and a half of clarified isinglass or gelatine; pour the cream into a mold previously oiled. Let it in rough ice and when it has become firm turn out on a dish.
Raspberries or currants may be substituted for strawberries.
