A cook is a kitchen worker who typically prepares food, such as meat, poultry, fish, and vegetables.
Cooks are employed by restaurants and other food service providers, private households, and other institutions such as prisons and the military.
Cooks may specialize in a particular food, such as meat, fish, vegetables, or poultry, and may cook more or less of each type of food.
Cooks may be responsible for preparing meals for large numbers of people, or they may prepare meals for smaller groups.
Cooks also may be responsible for storing food, maintaining the kitchen, and supervising other kitchen workers.
