Sift together 1 cup flour, baking powder, salt and sugar. Combine egg and milk, 2 teaspoons shortening or oil. Add to dry ingredients; mix well to make batter. If bananas are large, cut in pieces; roll in the 1/4 cup flour then coat completely in batter. Fry in hot, deep fat (375 degrees) for 4 to 6 minutes, turning the fritters to brown evenly. Drain. Serve hot.
