Bring a large pot of water to a boil and add 12 gyoza dumplings. Stir right away to prevent the dumplings from sticking together.

When the water has returned to a boil, and the gyoza have floated to the surface (~1 minute), transfer them to the soup with a slotted spoon.
Continue cooking the gyoza in the soup for another 2-3 minutes. If you are using frozen dumplings, you'll want to cook them for a little longer.
Finish the gyoza soup by adding 30 grams scallions and 1 teaspoon toasted sesame oil, and serve it by dividing it between 2 large bowls.
