For best results, do not overmix the dough. When sealing the pierogi, ensure the edges are tightly crimped to prevent filling from escaping during boiling. Pierogi can be made ahead and frozen; simply place them on a floured baking sheet in a single layer until solid, then transfer to a freezer-safe bag. Cook from frozen in boiling water. Serve with a dollop of sour cream, crispy fried onions, or even some bacon bits for an extra treat.
