An egg wash is a mixture of beaten eggs and a liquid, typically water or milk, that is used to brush on the surface of baked goods before baking. It is often used to give a glossy appearance, enhance browning, and provide a seal or glue for toppings or decorations.
An egg wash can be used on various baked goods, such as pastries, bread, and pies. It helps create a shiny and golden brown crust on the surface of the baked item. Additionally, it can act as an adhesive for sprinkling toppings like sugar, seeds, or nuts.
When it comes to pancakes, an egg wash is not typically used. Pancake batter is usually made with a combination of flour, eggs, milk, and other ingredients. Baking powder is often added to the pancake batter to help it rise and become fluffy. Baking powder provides the leavening action in pancakes by releasing carbon dioxide gas when it reacts with the liquid and heat during cooking.
While an egg wash can be used on some breakfast pastries like croissants or danishes, it is not necessary or commonly used on pancakes. The fluffiness and texture of pancakes primarily come from the leavening agents in the batter, such as baking powder, and the cooking technique employed.
