Strawberry Hard Sauce

Stir 2 tablespoonfuls butter to a cream with 1 cup powdered sugar; add the yolks of 2 eggs; beat until very light and stir 1 cup nice, ripe strawberries through it; put the sauce in a glass dish, cover with the beaten whites of 2 eggs and put some nice strawberries on top of the sauce. Any other kind of fruit may be used instead of strawberries. Or stir ½ cup butter with 1 cup powdered sugar to a cream; add the beaten white of 1 egg and 1 cup thoroughly mashed strawberries.
