Ingredients

2 cups all-purpose flour 

1/4 cup sugar 

1/2 teaspoon salt 

1 1/4 cups (2 1/4 sticks) unsalted butter, room temperature 

1 large egg yolk 

Preparation

In the bowl of a heavy-duty mixer fitted with the paddle attachment, mix flour, sugar, and salt on medium-low speed to combine. Add butter, and continue mixing until coarse crumbs form. Add egg yolk; mix just until dough comes together. Roll dough out, about 1/8 inch thick, between two layers of parchment paper. Chill until firm, about 1 hour.
