I noticed recently that my local Xi’an Famous Foods no longer lists its sensational Spinach Dumplings in Hot and Sour Sauce as being vegan. The staff confirmed that they haven’t added added egg or shrimp to the fillings but told me they boil the vegetable dumplings in the same water as the lamb dumplings and so took away the vegan indicator on the menu. So I would term these dumplings as “vegan adjacent”.
Nearby at Grain House the vegetable dumplings are vegan and delicious. I reviewed Grain House about a year ago, shortly after it opened, and gave its Spicy and Numbing Pork Wontons and Pork Potstickers lots of love. The steamed vegetable dumplings, which appear to be house made, are as good or even better than the Pork Potstickers. The wrappers are just thick enough to be chewy without being doughy and envelope a tasty mix of tofu, cabbage, carrot, glass noodles and maybe mushroom.
