Bring a large pot of water to a rolling boil. You'll need enough water to cover the dumplings completely.
Add the frozen dumplings to the pot, making sure they are submerged in the water.
Stir the dumplings gently with a slotted spoon or spatula to prevent them from sticking to the bottom of the pot.
Boil the dumplings for about 8-10 minutes or until they float to the surface of the water. You may need to adjust the cooking time depending on the size and thickness of the dumplings (Vegetarian and Vegan dumplings takes less time to cook).
Use a slotted spoon or strainer to remove the dumplings from the pot and place them on a plate.
Serve the dumplings hot with a dipping sauce made from soy sauce, vinegar, and a small amount of sesame oil (optional).
Be sure not to overcrowd the pot when cooking the dumplings, as this can cause them to stick together and cook unevenly.
You can also pan-fry or steam the dumplings if you prefer. To pan-fry, add a small amount of oil to a non-stick pan over medium-high heat and cook the dumplings until they are golden brown on both sides. To steam, place the dumplings in a steamer basket over boiling water and steam for about 9-12 minutes.
Experiment with different dipping sauces to find your favorite flavor combination. Some popular options include chili oil, hoisin sauce, black vinegar, and ginger scallion sauce.
