I ended up going to the PNA. Found out that's where my father's family would go like 3x a week when he was a kid. This whole search for pączki has sent me down a rabbithole of family associations and history, and it's rather delightful.

Anyway. Y'all. Those folks know what they're doing. Bought golabki for dinner as well. Darned tasty meal - they do a better job with the rolling technique than we do at home. Thanks for the recs!
