Offals
Of course, the Pennsylvania Dutchman has to note that one of the famous dishes using offals is scrapple, which is basically cornmeal mush with the addition of the offals from slaughtering a hog. While there are those, including many non-Dutchmen, who love it, I can't stand the stuff. It comes in large bricks, which you slice and fry. When you're frying it, it smells like the town garbage dump is on fire.

Now on the other hand, tripe is really something else. There is a dish native to Philadelphia called Pepper Pot. It's a soup and includes small pieces of tripe. One of my favorites.

And then there is Tripes a la mode de Caen -- my mouth is watering just thinking about that.
