To a pot, add water and ingredients required for soup jelly.
Bring to a boil and transfer to a container. Let it cool and refrigerate overnight.
In a mixing bowl, combine all the filling ingredients: ground vegan pork, sesame oil, white pepper, chili flakes, grated ginger, and chopped green onions.
Chop the solid soup jelly into small cubes and add them to the filling. Mix until well combined.
Place a spoonful of filling in the center of each dough circle. Carefully pleat and seal the edges of the dough to form a dumpling, ensuring there are no gaps.
Line a steamer basket with parchment paper or cabbage leaves to prevent sticking.
Place the assembled dumplings in the steamer basket, leaving space between each dumpling to prevent them from sticking together.
Steam the dumplings over boiling water for about 8 minutes - do not over steam if not the soup will come out of the dumplings.
Carefully transfer the steamed soup dumplings to a serving plate using a spatula or chopsticks.
Serve hot with dipping sauce, immediately.
Pierce the dumplings with a chopstick or a soup spoon to release the flavorful broth inside before taking a bite.
