Cheese sauce is a sauce made with cheese or processed cheese as a primary ingredient. Sometimes dried cheese or cheese powder is used. Several varieties exist and it has many various culinary uses. Mass-produced commercial cheese sauces are also made by various companies, in both liquid and dry forms. These prepared sauces are used by consumers and restaurants, and commercial formulations are used in the production of various prepared foods, such as macaroni and cheese mixes and frozen meals.

A dip or dip sauce is a common condiment for many types of food. Dips are used to add flavor or texture to a food, such as pita bread, dumplings, crackers, chopped raw vegetables, fruits, seafood, cubed pieces of meat and cheese, potato chips, tortilla chips, falafel, and sometimes even whole sandwiches in the case of jus. Unlike other sauces, instead of applying the sauce to the food, the food is typically placed or dipped into the sauce.
