Combine shrimp, pork, green onions, corn starch, garlic, hoisin sauce, soy sauce and sesame oil in a medium bowl; set aside.
Place a rounded teaspoonful of pork mixture in the center of each wonton wrapper. Lightly brush edges of each wrapper with water. Gather edges of dough up around filling and pinch 3 or 4 times near the top to form a pouch, leaving filling exposed on top.
Boil 2 inches of water in a medium saucepan. Brush the botton of a bamboo OR metal steamer OR flat bottom colander lightly with oil; place 10 to 13 dumplings, 1-inch apart, in steamer.
Cover and steam 6 minutes or until filling is cooked through. Repeat until all dumplings are cooked. Serve with Soy Dipping Sauce.
