In nearby Pennsylvania, the Pennsylvania Dutch "walk the street across, and look the window in." Of course, the Dutch is truly Deutsch (that's German for German) and the sentence structure is German. Perhaps the same is true in Wisconsin. Just a little German influence.
Looking at everyone's recipe, polk weed looks like the vegetable version of tofu. Not much by itself, but if you mix it with good tastin' food, it helps out.
Eggs in bacon grease, or ham and tabasco sauce. A good start for just about any meal. Add polk weed or tofu, still a good meal.
