Juicy kimchi and cabbage dumplings with a crush-and-reserve technique that keeps the filling flavorful, not watery, and freezes beautifully.
Use well-fermented, sour kimchi for the deepest flavor — young kimchi won"t give you enough tang. Don"t skip reserving the squeezed-out liquid; it"s where most of the seasoning lives. For a vegetarian version, swap the pork for finely crumbled firm tofu that"s been pressed dry, and add an extra teaspoon of sesame oil for richness.
