I recently bought a smoker and in searching for old-time Polish sausage recipes I found a collection I think you will get a kick out of in browsing through. Comes from an old butcher supplier, B. Heller Co. Chicago. I think may still be in business, and this was meant for commercial butchers. Recipes for everything from all sorts of sausages to kraut to mincemeat. I really enjoyed browsing through and I bet you will too.
