Production or use of eggs (especially chicken eggs) as well as recipes including eggs and all products made from eggs.
Eggs are laid by oviparous animals as part of their reproductive cycle. Unfertilised eggs, especially those laid by chickens, are commonly included in diets and have a major role in many cuisines around the world.
Not all vegetarians consume eggs. In India, the vegetarian mark (green dot) labelling program considers products to be non-vegetarian if they contain eggs. However, in North America and Europe most vegetarians practice lacto-ovo vegetarianism which includes both dairy-products and eggs.
Many people consume eggs because of their nutritional properties. Eggs can also play an important culinary role in cooking and baking, especially as a binder. Eggs tend to have a distinctive sulphurous smell reflecting their high sulphur content.
Vegans and some vegetarians are likely to search for egg-substitutes.
