Cooking, cookery, or culinary arts is the art, science and craft of
using heat to prepare food for consumption. Cooking techniques and
ingredients vary widely, from grilling food over an open fire to using
electric stoves, to baking in various types of ovens, reflecting local
conditions. Types of cooking also depend on the skill levels and
training of the cooks. Cooking is done both by people in their own
dwellings and by professional cooks and chefs in restaurants and other
food establishments.
