RE: Fresh Polish Sausage - the best ever!
Even though I married into a Polish family I'm no expert. Looking on the Internet, kielbasa is the generic name for all Polish sausage but the way I've seen it, if it's labeled kielbasa it's a smoked suasage whereas what I call "real" Polish sausage is the raw meat mixture in a natural casing. Wikipedia says it's sometimes called white sausage. The link below has a good picture of what I'm talking about.
What you get from Ostrowki's in Balteemore/Balmer (Baltimore) is the "real" Polish sausage and is labeled Polish sausage. Oddly enough, Ostrowski's logo is "Homemade Polish Kielbasa" but their "real" Polish sausage always has "Polish sausage" on the label, not kielbasa. Now I'm confused myself. If you really want to know maybe you can e-mail John Ostrowski. Here are a couple of links to Ostrowski's kinda sorta web page.
