In a medium bowl, combine the pork, egg, green onion whites, garlic, ginger, and soy sauce. If desired, cook a tiny portion of this (about a tablespoon) in a saute pan to check the seasoning. If needed, add additional soy sauce or salt.
Using a small scoop, place about 1 teaspoon of filling in the center of a wonton wrapper. The amount of filling will depend on your wrapper. Don’t overfill, but make sure you have a nice filling to wrapping ratio. Get a small bowl of water and using your finger or a pastry brush, dampen 2 edges of the wrapper. Fold in half to form a triangle and seal, then fold in half again to form a cute little dumpling. Repeat with remaining pork. Any leftover filling can be cooked as meatballs or sautéed and crumbled in a pan for a lovely lettuce wrap filling or topping for a rice bowl.
For wontons, bring a pot of water to a boil. Add wontons and simmer gently, until fully cooked, about 5-6 minutes. They should float when done.
To make potstickers, heat a nonstick pan over medium heat. Add a tsp of oil and add as many potstickers that will fit in a single layer. Cook over medium heat until nicely browned and crisp on the bottom, about 3-5 minutes. Add about 2 tbsp water to the pan (it will sizzle) and cover with a lid. Allow to steam cook for an additional 5 minutes or so. Uncover and cook until any additional water evaporates. Enjoy just as they are or with Dipping Sauce, below.
For Dipping Sauce, combine everything in a bowl and stir to dissolve the sugar. Enjoy!
