Do you make your potsticker wrappers or buy them?

Agree. Hand made wrappers are BEST.
Flour + warm water, knead and let rest.
Shape dough into rope, cut pieces, roll circles; fill and pleat.
The wraps taste better and are easier to stuff and pleat. Tender and silky delicious potstickers.

This same dough works for green onion pancakes if you add salt, chopped green onions, and sesame oil.
