Some packaged dumpling skins (a.k.a. gyoza or wonton wrappers) contain eggs. Some don’t, but they’re so easy to make, why not be sure they’re egg-free? Plus, they taste amazing made fresh, especially for soup dumplings. Dust the skins generously with flour or cornstarch and you can stack and refrigerate them for a week or freeze them for months.
