Eggs are a complete protein source containing all nine essential amino acids, and rich in choline, selenium, and lutein; the yolk provides vitamins A, D, and B12, while the white is nearly fat-free.
About
An egg is the reproductive body produced by the female of avian species, most commonly the domesticated chicken (Gallus gallus domesticus), consisting of a protein-rich white (albumen) and nutrient-dense yolk enclosed within a calcium carbonate shell. Eggs have been a dietary staple across cultures for millennia, prized for their nutritional completeness and versatility.
Chicken eggs vary in size from small to jumbo, with shell colors ranging from white to brown to speckled, determined by breed rather than nutritional content. The yolk contains fat-soluble vitamins and cholesterol, while the white provides high-quality protein and minimal fat. Other common culinary eggs include duck, quail, and goose eggs, each with distinct flavor profiles and cooking characteristics.
Culinary Uses
Eggs function as a foundational ingredient across virtually all culinary traditions, serving as binder, leavening agent, emulsifier, and primary protein source. They are prepared through countless methods: poached, fried, scrambled, baked, boiled, or used in omelets and custards. In baking, eggs provide structure, moisture, and lift to cakes, pastries, and breads. They serve as the base for mayonnaise, hollandaise, and other emulsified sauces, and are essential to pasta dough, meringues, and mousses. Eggs appear across global cuisines in diverse forms: shakshuka in Middle Eastern cooking, frittatas in Italian cuisine, fried rice throughout Asia, and countless egg-forward breakfast traditions in Western cooking.
