When pan-frying, use a non-stick pan. Preheat your pan and use a little more oil before placing frozen dumplings in your pan. The coating on frying pans can vary and may not be as effective depending on the age of the pan. Be sure not to let the dumplings sit too long in a heated pan after the water has evaporated.
If steaming, it is recommended not to place the frozen dumplings directly on the bottom surface of the pan or in direct contact with the water.
Place the dumplings in your pan or steamer with some space in between so that they do not touch each other. Dumplings will expand when cooking.
