Vanilla custard is a smooth and creamy dessert made primarily from milk, sugar, and eggs. It is flavored with vanilla, which gives it a rich and aromatic taste. The mixture is gently cooked until it thickens, creating a velvety texture that can be enjoyed on its own or used as a filling for pastries and tarts. This versatile custard can be served warm or chilled and is often used in various desserts, such as puddings and cakes. It can also be a base for other flavors, making it a popular choice in many culinary creations.
