In a large mixing bowl, sift the flour, sugar and salt. Add the chilled butter and cut in with a pastry blender, to resemble coarse meal.
Stir egg yolks, vanilla extract and water together in a small bowl and add it to the flour mixture, blending in with a fork. Shape sough into a ball, working quickly.
Place the ball of dough on a pastry board. With the heel of your hand, push about 1/4 cup of dough away from you into a 6 to 8-inches thin streak of dough; repeat until all the dough has been smeared. Scrape dough together; re-form a ball, wrap in wax paper and chill for 2 to 3 hours.
Roll your dough between 2 sheets of wax paper or a floured pastry cloth and a floured cloth cover on your rolling pin.
