Cooking or cookery is the art, technology and craft of preparing food for consumption with or without the use of heat. Cooking techniques and ingredients vary widely across the world
from grilling food over an open fire to using electric stoves, to
baking in various types of ovens, reflecting unique environmental,
economic, and cultural traditions and trends. The ways or types of
cooking also depend on the skill and type of training an individual cook
has. Cooking is done both by people in their own dwellings and by
professional cooks and chefs in restaurants and other food
establishments. Cooking can also occur through chemical reactions
without the presence of heat, such as ceviche is a traditional South America dish where cooked with the acids in lemon or lime juice.
