Prepare the Dough:
Combine flour and salt in a mixing bowl. Gradually add hot water, stirring until a dough forms.
Knead the dough on a floured surface until smooth, about 5-7 minutes. Cover with a damp cloth and let it rest for at least 30 minutes.
Make the Broth:
Prepare a flavorful vegan broth using vegetable stock, soy sauce, ginger, and garlic. Simmer to combine flavors, then cool it down and refrigerate until it firms up.
Prepare the Filling:
Finely chop your choice of vegetables, such as shiitake mushrooms, napa cabbage, and carrots. Sauté them with garlic, ginger, and soy sauce until soft.
Assemble the Dumplings:
Roll out the rested dough into thin circles. Place a spoonful of filling and a small cube of the firmed broth in the center of each circle. Carefully pleat the edges to seal the dumplings.
Cook the Dumplings:
Steam the dumplings in a steamer basket lined with parchment paper or cabbage leaves for about 10-15 minutes, or until the dough is translucent and cooked through.
Serve:
Serve hot with a dipping sauce made from soy sauce, vinegar, and chili oil.
