Line a large plate or pan with parchment paper. Then, arrange the crystal dumplings over the large plate or pan, making sure that the dumplings don’t touch each other. They will be difficult to break apart if they stick together.
You do not need to defrost the dumplings before you cook them. Just steam them like you would fresh dumplings, but steam them for 7 to 8 minutes on high heat.
The dumplings will crack slightly once frozen (see photo above). Don’t worry about the cracks. They will seal up as the dumplings steam.
