Miss_thenorth and Cassandra,
The pronunciation thing is that it's a Pasty, rhymes with Nasty. But when you write Pasties, it looks the same as those things go-go dancers wear, even though you pronounce it PASS-teez.
It's not really like a hot pocket... more like a thick stew wrapped in dough, semi-circle shaped. The inside is usually like a solid mass of beefy potatoey goodness. It's a Cornish thing, from Cornwall England, that somehow made its way into the food culture of Northern Wisconsin, Michigan, and Minnesota. I think it was supposedly invented as food for miners, so they could take hearty stews with them to work.
