Sables (Norman Sugar Cookies) - cooking recipe

Ingredients

2 cups flour
8 tablespoons unsalted butter, cold
1/2 cup sugar
5 egg yolks
1/4 teaspoon salt
1 teaspoon vanilla
2 tablespoons milk

Preparation

Sift the flour and the sugar into a large bowl and add the butter, bit by but, mixing with an electric mixer or by hand.
Continue mixing until the dough takes on a sandy consistency.
Add four of the egg yolks, one by one, the salt and the vanilla, continuing to mix.
Form the dough into a ball, wrap in plastic, and refrigerate for at least an hour.
Pre-heat the oven to 350 degrees.
Roll out the dough to a thickness of 1/4\".
With a cookie or biscuit cutter (or a small glass) cut out two inch circles and place on a lightly buttered cookie sheet.
Mix the remaining egg yolk with the milk and, with a pastry brush, coat the top of each cookie.
With the tip of a small knife, score 6 or 7 stripes on each cookie.
Bake for 15 minutes or until lightly browned.
Remove from oven, cool on a rack and store in an airtight container.
