Pastry chefs use egg washes on baked goods such as cutout cookies mostly to lend shine, according to Fine Cooking magazine, but the egg yolk also produces a golden hue.

If you want your cookies to have more visual interest or to complement the color scheme of a particular occasion, add food coloring to your egg wash. Decorative sugar sprinkled on top of the wash makes for a dramatic sparkle.
Things You'll Need
- Crack open an egg, place the contents into a bowl and discard the shell.
- Beat the egg with a fork until the yolk and white are mixed well and the liquid is a uniform color.
- Add 1 teaspoon of water to the egg mixture and beat again. If you want to tint your egg wash, add food coloring drop by drop until you achieve the desired color.
- Brush the mixture onto the tops of your unbaked cookies with a pastry brush. Sprinkle the cookies with colored or turbinado sugar if you wish.
- Bake your cookies as usual.
Use the egg white alone if you want the cookies to have a clear shine.
