French Beans à la Crême.

Open a can of string-beans; clip them into short pieces, and cook twenty minutes in hot salted water. Drain. Have ready, in a saucepan, two tablespoonfuls of cream, and as much butter, heated together; pour upon a beaten egg; return to the saucepan; season with pepper and salt; stir in a tablespoonful of hot vinegar; take from the fire; dish the beans, and pour the sauce over them.
