A grater is a kitchen utensil used to grate foods into fine strips or crumbs. Several types of graters boast 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 (to create zest), and can also be used to grate other soft foods.
They are also known as shredders in Eastern America.
A nutmeg grater is a tiny grater with very small holes. It is used to grate nutmeg over eggnog, other creamy and frothy drinks, and any other food in which nutmeg can be used to garnish or add flavour.
The side of a cheese grater with the smallest holes will usually grate nutmeg perfectly well.
