Melt the butter and set aside.

Mix the sugar with the egg yolk until you get a wet crumbly mixture.

Add the flour until you get a dry sandy texture.

Add the melted butter and stir until the dough sticks together (do not over mix).

Chill the dough 1 hours or until firm, or not! I never have the patience

Take a pinch of dough and form a 1” ball that you place on a lightly buttered cookie sheet.

Flatten each cookie to ¼” with the flat bottom of a glass, or a cookie stamp as I did.

If they stick, lightly flour the dough rather than oiling like I did!

Bake at 375F (190C) for 10-12 minutes or until lightly golden around the edges.

If you want a more even look, try shaping the dough into a cylinder in plastic wrap and chilling thoroughly before slicing and baking.
