Cut each piece of sparerib into 1-½ inch long pieces. Heat 3 tablespoons of oil. Stir fry the spareribs, 2 pieces of scallion, and ginger for about 1 minute. Splash in the wine, soy sauce, sugar and 3 cups of boiling water. Cover the pan tightly and stew over low heat about ½ hour until the sauce is reduced to 1 cup.
