About
A fresh egg is the reproductive body produced by female fowl, typically chickens (Gallus gallus domesticus), consisting of a hard calcified shell, albumen (egg white), and yolk enclosed within a protective membrane. Chicken eggs are the most commonly consumed eggs worldwide, though duck, quail, goose, and other poultry eggs are used in various culinary traditions. A fresh egg has a rounded or oval shape with a porous shell that ranges from white to brown in color depending on breed. The yolk, comprising approximately 30% of the egg's weight, is rich in fat and nutrients and ranges in color from pale yellow to deep orange depending on the hen's diet. The albumen comprises approximately 60% of the egg's weight and consists primarily of water and proteins. Freshness is indicated by a firm white, centered yolk, and minimal air cell size, typically measurable within 7-10 days of laying.
Culinary Uses
Fresh eggs are fundamental to nearly all cuisines, serving functions both as a standalone dish and as a binding, emulsifying, leavening, or enriching ingredient. Eggs are prepared through diverse cooking methods including frying, scrambling, boiling, poaching, and baking. They form the base of omelets, frittatas, custards, and countless baked goods from cakes to pastries. In classical French cuisine, eggs are essential to béarnaise and hollandaise sauces, mayonnaise, and mousses. Raw or lightly cooked eggs appear in Caesar salad dressings, carbonara, and tiramisu. Beaten eggs create structure in soufflés and meringues, while whole eggs bind ingredients in meatloaf and croquettes. The yolk and white can be used separately or together depending on the application, with whites valued for meringues and yolks for custards and emulsions.
