Egg wash is a mixture, usually of beaten egg and a liquid such as water, milk, or cream, brushed onto baked goods before or during baking to glaze, seal, or adhere toppings.
The origins of egg wash can be traced back to ancient civilizations, where it was used as a glaze for baked goods and a sealant for pastries. The practice of using egg wash likely emerged as a way to enhance the appearance and texture of baked items, as well as to create a protective barrier against moisture and drying.
Egg wash is primarily made by whisking together whole eggs or egg yolks, sometimes with the addition of water, milk, or cream. The most common sources of eggs used in egg wash are from chickens, although other poultry, such as ducks and geese, can also be used.
In the culinary realm, egg wash serves multiple purposes. It is widely used to achieve a glossy, golden-brown finish on breads, pastries, and other baked goods. The egg wash acts as a sealant, helping to prevent the dough from drying out and creating a crisp, flaky crust. Additionally, egg wash can be used to adhere toppings, such as seeds or nuts, to the surface of baked items, ensuring they stay in place during the baking process.
The flavor profile of egg wash is relatively neutral, with a subtle richness and slight eggy taste. This makes it a versatile ingredient that can be used in both sweet and savory applications without overpowering the other flavors. Egg wash pairs well with a wide range of ingredients, including herbs, spices, cheeses, and even some fruits and vegetables.
In Western cuisines, egg wash is commonly used in the preparation of croissants, puff pastries, pie crusts, and various bread products, such as dinner rolls and braided loaves. In Asian cuisines, egg wash is often used to create a shiny, golden-brown finish on steamed buns, dumplings, and other baked goods.
Complementary ingredients that pair well with egg wash include butter, milk, cream, and various herbs and spices, such as rosemary, thyme, and paprika. These ingredients can be incorporated into the egg wash mixture or used as toppings to enhance the overall flavor and appearance of the baked item.
