Garlic sauce

Garlic sauce is a sauce prepared using garlic as a primary ingredient. It is typically a pungent sauce, with the depth of garlic flavor determined by the amount of garlic used. The garlic is typically crushed or finely diced. Simple garlic sauce is composed of garlic and another ingredient to suspend the tuber via emulsion, such as oil, butter or mayonnaise. Various additional ingredients can be used to prepare the sauce.
Garlic sauce can be used to add flavor to many foods and dishes, such as steak, fish, seafood, mutton, chops, chicken, eggs and vegetables. It is also used as a condiment.
