Cheese Quiche

In a bowl, mix the flour with a pinch of salt. Add the cold butter and work it into the flour with your fingers or a pastry blender until the mixture resembles coarse breadcrumbs.

Add the egg yolk and 2-3 tablespoons of cold water. Mix quickly until the dough comes together. If the dough is too dry, add a little more water.

Form the dough into a ball, wrap it in plastic wrap, and let it rest in the refrigerator for 30 minutes.
