Galette Dough

In a bowl, mix the flour with the sugar and salt. Using a pastry blender or your fingers, cut in half of the butter until the mixture resembles coarse meal. Cut in the remaining butter until the largest pieces are the size of lima beans. Drizzle the water over the dough and stir until moistened. Gather up the dough and knead it 2 or 3 times. Flatten the dough into a disk, wrap in plastic and refrigerate for at least 30 minutes.
