A grater is a kitchen utensil used to grate foods into fine pieces.
Several types of graters feature different sizes of grating slots, and can therefore aid in the preparation of a variety of foods. They are commonly used to grate cheese and lemon or orange peel, and can also be used to grate other soft foods. They are commonly used in the preparation of toasted cheese, Welsh rarebit, and dishes which contain cheese sauce such as macaroni and cheese, cauliflower cheese.
In Slavic cuisine, graters are commonly used to grate potatoes, for preparation of, e.g., draniki, bramborak or potato babka.
In tropical countries graters are also used to grate coconut meat.
Graters produce shreds that are thinner at the ends than the middle. This allows the grated material to melt or cook in a different manner than the shreds of mostly uniform thickness produced by the grating blade of a food processor. Hand-grated potatoes, for example, melt together more easily in a potato pancake than food-processed potato shreds.
