Custard is a creamy dessert made from a mixture of milk or cream, sugar, and egg yolks. It is often thickened by cooking over low heat, which allows the eggs to coagulate and create a smooth texture. Custard can be served warm or cold and is a versatile base for many desserts, including crème brûlée and flan. There are two main types of custard: stirred and baked. Stirred custard is cooked on the stovetop and continuously stirred until it thickens, while baked custard is poured into a dish and cooked in the oven. Both types can be flavored with vanilla, chocolate, or fruit, making them popular choices for various sweet treats.
