2 tsp. cornstarch
1-2 tsp. sugar, optional

1 recipe Shau Mai Dipping Sauce
In a large bowl, mix together water chestnuts, scallions, shrimp, sesame oil, peanut oil, sherry wine, cornstarch, sugar, if desired, salt, and pepper.
Using a knife, trim the edges of each wonton wrapper to form a round. Place 1 Tbsp. filling in the center of each wrapper; moisten edges with water.
Cup your hand around wrapper, gathering folds up and around the filling. Press gathered folds lightly around filling to adhere.
