Hawaii's version of Chinese shumai is Pork Hash. These steamed dim sum treats contain pork and shrimp. Super soothing and delicious. Enjoy with soy sauce/hot mustard.
Make the filling first! In a mixing bowl, combine pork, shrimp, egg, water chestnuts, green onions, garlic cornstarch, soy sauce, oyster sauce, sesame oil, and white pepper.
Assemble the pork hash now. Fill the center of the dumpling skin with a small spoonful of the filling. Fold the edges up and wrap them around the filling, leaving the top open/exposed. Rep this step until all of the filling has been used up.
For 20 minutes, steam.
To serve, drizzle the pork hash with soy sauce...or, as we do in Hawaii, a mixture of soy sauce and hot mustard. Eat quickly and enjoy_
