Custard is a variety of culinary preparations based on a cooked mixture of milk or cream and egg yolk. Depending on how much egg or thickener is used, custard may vary in consistency from a thin pouring sauce (crème anglaise) to a thick pastry cream (French: crème pâtissière) used to fill éclairs.
Rice pudding is a dish made from rice mixed with water or milk and other ingredients such as cinnamon and raisins. Variants are used for either desserts or dinners.
