Put two tumblers of white roux and one of chicken jelly into a saucepan, reduce, and add three yolks of eggs mixed with two ounces of butter and the juice of one-half lemon. Before it boils take the saucepan off the fire, and add one tumbler of thick tomato sauce (see Sauces, page 30), strain, and just before serving add one tablespoon of sweet herbs minced fine.
