Prepared materials: non-stick pan, cooking oil.

Step 1: Prepare a pan, preferably non-stick, so that the dumplings are easier to heat evenly. Add a little oil to the pan, then arrange the dumplings from the refrigerator. Turn the heat on high. When the pan starts to heat up, add water to the pan, bringing the water level to a little over 1/3 of the way up the gyoza.

Step 2: Cover the pan with a lid and turn the heat up to medium. When you hear the pan start to sizzle, the water in the pan is almost dry, so open the lid and turn the heat up to high, and use chopsticks to separate each dumpling from the other so they don't stick together. When the water evaporates and the dumplings start to dry out, it's time to cook.

Step 3: The whole process usually takes about 15 minutes, which is also very fast. If you fry the dumplings for too long, the juices inside the dumplings will flow out, resulting in a big loss of flavor.
