For the US, I’d say a pretty strong contender is Woodstock, NY, with a population of around 6,000, and of course famous for the music festival of the same name (even though the actual festival was something like 60 miles away in Bethel)

Also, if you can it helps to get multiple people involved and do big batches, then freeze them for later.

Once a year (this Sunday actually) I get together with some family and friends and make a ton of pierogies

People come with premade fillings, and we divide up the work, some people making dough, others rolling it out, someone filling them, another person bagging them up, etc.

We also use something like this so we can bang out 18 pierogies at once, lay down a sheet of dough, spoon filling into them, another sheet on top, roll over it with a rolling pin and you’ve got pierogies.
