To make each dumping, wet all edges of one wonton wrapper. Place roughly 1 1/2 tablespoons of filling in the center of the wrapper. Close all four sides around filling and squeeze together at the top, creating a pouch. Repeat for remaining wrappers, keeping finished dumplings cover to prevent wrappers from drying. Hold refrigerated or freeze until service.
Bring a pot of water to a boil. For each serving, boil 7 dumplings until cooked through. Pull from water and place on desired plate.
Stir black vinegar sauce well. Top cooked dumplings with 1/4 cup of sauce. Garnish as desired. Serve warm.
This black vinegar sauce can be served on any type of dumpling.
