The Polish sausage of my childhood was a smoky, juicy, finely-textured meaty thing with mustard seeds scattered randomly throughout. Once I moved away I never tasted it again until one weekend, at the monthly flea market in Nashville, there was a guy who'd brought a whole bunch down from Arthur, Illinois. He was handing out samples which apparently weren't going over so well with the Nashville crowd, but one taste told me what I wanted to know. If I could have I'd have bought him out and worried about freezer space later, but I was too broke to buy more than a couple of pounds. As that was just about all he sold that day he never came back.
Okay, so now I have online sources for the Tennessee-style meats I want - anyone know of any similar enterprises in downstate Illinois? Chicago-style kielbasa is pretty close, but those Amish co-op guys did the best I've ever tasted.
