I have a small freezer and it's full of Ling Ling brand Pot Stickers.
You're right, if you have space the freezer is fine. Comparison of freezer storage vs shelf stable------- I wonder which one might result in less loss of flavor. I have to open my log cheung and repackage them into 2-or 3 packages because I cook just for one or two people. (Which has nothing to do with the shelf stable option. Just noodlin'.)
Speaking of....... I imagine that an opened package would keep a long time NOT FROZEN if wrapped carefully. Never mind.
