Prepare the Filling: In a large bowl, mix together the ground beef, chopped celery, minced garlic, grated ginger, and soy sauce until everything is well combined.
Assemble the Dumplings: Place about one tablespoon of filling in the center of each dumpling wrapper, moisten the edges with water, fold and pinch to seal.
Cook the Dumplings: Steam in a steamer basket for 10-12 minutes or pan-fry in a skillet over medium-high heat until golden brown.
Make the Dipping Sauce: In a small bowl, whisk together rice vinegar and chili oil.
Serve: Gather dumplings on a plate, serve hot with dipping sauce on the side.
Notes
Ensure dumplings are sealed tightly to prevent opening during cooking. Dumplings can be frozen before cooking.
