When I was growing up, my mom always decorated our shortbread cookies with egg yolk paint. It makes for amazing decorative colouring on cookie designs.
Here is the recipe:
- 1 egg yolk
- 1/4 teaspoon room temperature water
- food colouring
Mix the egg yolk and water together with lots of food colouring.
Use a paint brush to brush onto baked cookies. The cookies must be returned to the oven until the egg is solidified.
