Roll into a rectangle 1/4 inch thick and cut into squares. Heat oil in a deep fryer and drop squares into oil, turning so they will puff evenly. Brown on both sides, drain on paper towels. You can make the dough up to 6 hrs in advance and fry when ready to eat.
NOTE: Traditionally, sopapillas are served warm with honey, or they may be rolled while hot in a mixture of 1/2 cup powdered sugar mixed with 1 teaspoon cinnamon.
