What is a egg wash?

An egg wash is a mixture of beaten egg and sometimes water or milk that is brushed onto baked goods before baking to give them a shiny, golden-brown crust. It is commonly used on pastries, breads, and pies to enhance their appearance and add flavor.

The protein in the egg helps to create a glossy finish while the fat in the yolk creates a rich color when baked. The addition of water or milk can help to thin out the egg mixture and make it easier to brush onto the surface of the baked goods.

To make an egg wash, simply beat one or more eggs with a small amount of water or milk until well combined. The mixture can then be brushed onto the surface of the baked goods using a pastry brush before baking.

Egg wash can also be used to help toppings such as seeds or sugar adhere to the surface of baked goods. It is a versatile ingredient that can help to improve the appearance and texture of a wide variety of baked goods.
