3 T. vegetable oil
1 leek, cleaned and thinly sliced
1 clove garlic, pressed
1 head Napa cabbage, finely shredded
½ pound of cleaned shrimp diced in a medium dice
2 T. rice wine vinegar
2 tsp. soy sauce
1-inch piece fresh ginger, peeled and grated
1 medium carrot, grated on finest holes of a box grater
24 wonton wrappers

Dipping Sauce

1/4 C. light soy sauce
2 T. rice wine vinegar
1/2-inch piece fresh ginger, peeled and finely grated
1 tsp. sugar
1/2 tsp. toasted sesame oil
1/2 lemon, zested

Stir all dipping sauce ingredients together in a small bowl until sugar is dissolved. Refrigerate until ready to serve. Heat 2 T. of the oil in a large nonstick skillet over medium-high heat. Add the leeks and garlic and cook until leeks begin to soften, about 3 to 4 minutes. Add the cabbage, vinegar, soy sauce, and ginger and cook, stirring, until cabbage is soft, about 3 to 4 minutes more. Remove from the heat and stir in the carrot and shrimp. Allow the filling to cool. Transfer cabbage mixture to a mixing bowl and work together until fully incorporated. Keep refrigerated until ready to use. To make the potstickers, lay a wonton wrapper on the work surface and put about 1 T. of the filling in the center. Dip your finger in a little water and wet the edges of the wonton wrapper; this will help the potsticker seal when cooking. Bring the outside edges of the wonton wrapper together over the filling and press it together to form a pouch. Continue with the remaining wrappers and filling. To cook the potstickers, heat the remaining oil in a very large skillet over high heat. Place all of the potstickers upright in the pan and cook, without disturbing them, until browned on the bottom, about 1 to 2 minutes. Add 1/2 C. water to the pan and immediately cover. Allow the potstickers to steam for about 3 minutes, then remove the skillet lid. Continue cooking until the water is completely evaporated. Transfer to a platter and serve with the dipping sauce.
