In a large bowl, combine flour, 2 tablespoons sugar and 1 teaspoon salt. Using a pastry blender or your fingertips, cut or rub in butter until mixture resembles coarse meal. Sprinkle 1 tablespoon ice water over part of the flour mixture; toss gently with a fork. Push moistened dough to side of bowl. Repeat with additional water, 1 tablespoon at a time, until all of the flour mixture is moistened but not sticky. Gather mixture into a ball. (Do not knead!) Gently flatten the ball into a disk and wrap disk with plastic wrap. Refrigerate dough 2 hours or overnight.
