1. In a blender, process water chestnuts until minced. Transfer to a large bowl; add sausage and mix well. Shape into 1-in. balls.
2. Place meatballs on a greased rack in a shallow baking dish. Bake, uncovered, at 350° for 20-25 minutes or until a thermometer reads 160°.
3. Meanwhile, in a large saucepan, combine the cornstarch, syrup, vinegar and soy sauce; stir until smooth. Bring to a boil; cook and stir for 2 minutes or until thickened and bubbly. Drain meatballs; add to sauce and heat through. Yield: 12-14 servings.
