Pound coriander roots, black peppercorns, and garlic with a mortar and pestle.

Combine golden mountain sauce, white sugar, sesame oil, and oyster sauce in a mixing bowl.

Add ground pork into a blender or food processor with your sauce mixture, egg, and tapioca starch. Pulse until it reaches a smooth texture that will be easy to spoon into the dumpling wrappers.

Transfer the ground dumpling filling mixture to a large mixing bowl and thoroughly combine with the crushed spice mixture of step 1 and your finely diced vegetables.

To easily shape the dumplings, place a wonton wrapper over the concave side of a tablespoon, press gently to create a well, add the filling to the center, lightly moisten the edges of the wrapper with water, then fold the edges up and around the filling, pinching to seal while nestled in the spoon to maintain the perfect shape.

Prepare your steamer by lining it with parchment paper to prevent sticking. Cover and steam over medium heat for 10 minutes until they’re cooked through, and the wrappers are translucent. Enjoy hot.
