White sauces are a category of sauces that are typically creamy and smooth in texture. They are often made from a base of butter, flour, and milk, which are combined to create a roux that thickens the sauce. Common examples include béchamel, which is used in dishes like lasagna and macaroni and cheese, and Alfredo, often served with pasta. These sauces serve as a foundation for many recipes and can be flavored with various ingredients such as cheese, herbs, or spices. White sauces are versatile and can enhance the taste and texture of a wide range of dishes, making them a staple in many cuisines.
