Step 1 Mix flour, sugar and salt. Using food processor, pastry blender or hands, cut butter into flour until it resembles small peas. Mix yolks and water, and add to flour mixture, mixing just until incorporated. Wrap dough in plastic wrap and chill 1 hour.
Step 2 Roll out pastry 1/8 inch thick. Roll up on rolling pin and unroll in 9-inch pie tin. Trim off excess (it can be used for decorating edges). Set crust in freezer until filling is prepared. This will help crust edges retain their shape when baked.
