Mix same as Macaroons. Shape mixture, which is quite soft, in a long roll. Cut pieces from roll three-fourths inch long. Roll each separately in chopped nuts, at the same time shaping to form a crescent. Bake twenty minutes on a buttered tin sheet in a slow oven. Cool, and frost with Confectioners’ Frosting, made thin enough to apply with a brush, and flavored with lemon juice until quite acid. Other nuts may be used in place of almonds.
