Tender pork wontons are tossed in a bold Sichuan-style chili oil sauce with soy sauce, black vinegar, garlic, and sesame paste. They are silky, spicy, savory, and perfect as an appetizer, noodle-shop-style snack, or light meal.
Make the filling: In a mixing bowl, combine the ground pork, chopped scallions, sesame oil, soy sauce, Shaoxing wine, salt, sugar, peanut oil, water, and white pepper. Stir firmly in one direction for about 5 minutes, until the mixture becomes sticky and paste-like. You can also pulse it in a food processor for about 1 minute.
Fill the wontons: Place one wonton wrapper on a clean work surface. Spoon about 1 tsp of filling into the center, then lightly moisten the edges with water.
Shape each wonton: Fold the wrapper in half into a rectangle and press out any trapped air around the filling. Bring the two outer corners together, overlap them slightly, dab with a little water, and pinch firmly to seal.
Repeat with the remaining wrappers and filling. Arrange the finished wontons on a parchment-lined tray so they do not stick together. You should have about 18 wontons.
Prepare the sauce while the water heats: Bring a large pot of water to a boil. In a serving bowl, stir together the light soy sauce, Chinese black vinegar, chili oil, sesame paste, and minced garlic until smooth.
Cook the wontons: Stir the boiling water to create gentle movement, then add the wontons in batches if needed. Keep the water at a gentle boil and stir occasionally to prevent sticking. Cook for about 2 minutes, or until the wontons float and the wrappers look slightly translucent.
Finish and serve: Add 1/4 cup of the hot wonton cooking water to the sauce and stir to loosen it. Lift the wontons out with a slotted spoon, transfer them to the sauce, toss gently, and garnish with chopped scallions before serving.
Use fatty ground pork for a juicier filling; very lean pork can make the wontons dry. If sesame paste is unavailable, tahini is a workable substitute, though the flavor will be slightly different. Freeze uncooked wontons in a single layer, then transfer to a bag; cook from frozen and add 1-2 extra minutes. Avoid overfilling the wrappers, or they may burst while boiling.
