Whisk the flour, baking powder and salt together. Combine milk and water in a separate cup. Add to flour mixture and stir with a fork to mix well. You will have a soft dough. Flour your countertop well with the remaining ¼ cup flour and coat your hands, too. Shape the dough into a cylinder and cut into 4 pieces. Pat each piece out into a circle about ⅓" thick (1 cm) and 6" across.
Heat the oil to 350 degrees F and fry breads one at a time, for about 2 minutes on each side. Drain. Serve topped with beans, meat, cheese, and vegetables of your choice. Jalapeños must be pickled jalapenos.
