A creamy mixture made from lemon juice, sugar, butter and egg yolks. The ingredients are cooked together until the mixture becomes quite thick. When cool, the lemon curd becomes thick enough to spread and is used as a topping for breads and other baked goods. Various flavors of curd are available in gourmet markets and some supermarkets.
