Finely mince the shrimp until slightly sticky in texture. This helps the filling hold together better.
In a bowl, combine the minced shrimp, scallions, light soy sauce, Shaoxing wine, chicken powder, sesame oil, and cornstarch. Mix well until fully combined and slightly tacky.
Place a small spoonful of filling in the center of each wonton wrapper. Fold by bringing opposite corners together.
Arrange wontons in a steamer lined with parchment or lightly greased. Steam for 8–10 minutes, or until the shrimp is fully cooked and the wrappers turn slightly translucent.
Enjoy hot with your favorite dipping sauce.
