Directions: Write three fortunes on 1-by-3-inch pieces of paper. Preheat oven to 300 F. In a bowl, combine flour, cornstarch, sugar and salt. Blend in vegetable oil. Add egg whites, water and vanilla. Stir until smooth. Bake cookies one at a time. Drop 1/3 cup of batter on a greased cookie sheet. Spread evenly into a 10-inch circle. Bake in oven until cookie turns a light golden brown (about 13 to 15 minutes). Immediately place a fortune in the center of the cookie. Bring two opposite ends of the cookie together, grasp the ends of the folded cookie and gently pull together to crease. Hold folded cookie for 1 minute to maintain shape as it cools and becomes crisp.
