Cream sauce is a type of sauce that contains heavy cream as its primary ingredient. It can be made by whisking together cream with other ingredients such as butter, garlic, herbs or spices to create a rich and velvety texture. Cream sauces are often used in cooking to add flavor and moistness to dishes like pasta, chicken, fish or vegetables. They can also be served on the side as a dip for bread or used as a garnish for desserts.
