The peppery flavor of daikon is complemented by the taste of a sweet-and-sour sauce. Serve with grilled chicken or shrimp.
1. In a small bowl, combine the sugar, cornstarch vinegar, and soy sauce. Stir to dissolve the cornstarch and blend in the ketchup.
2. Cut the 2-inch lengths of daikon into julienne strips and set aside. Heat the oil in a wok or large skillet. Add the daikon and cook, stirring constantly, over high heat for 30 seconds. Sprinkle on the water by drops and continue stirring for 1 to 2 minutes or until the daikon begins to turn limp. Pour on the soy sauce mixture and stir until slightly thickened.
