how to make egg wash
Egg wash is the baker's secret and it's super-easy to make and use. 1  Set aside an extra egg as you're baking and whisk it up with a splash of cold water or milk until pale yellow and perfectly mixed. The ratio is usually no more than 1 tbsp liquid per egg, but recipes do vary so use what it calls for. The less liquid you add to the egg, the darker the egg wash. Just before your bread, pies or pastries go in the oven, use a pastry brush and paint them with a light, even coat of egg wash. When your dough bakes, the egg wash does too, creating a glossy sheen for that professional bake-shop look.
