What is the German name for a recipe for a stuffed pig stomach?

Question

I had not heard of this one before and since I am German I am curious.

Answer 1

Is this what you're thinking of?

Knipp (Speise) from Bremen and Lower Saxony, north Germany. Made with any animal leftovers, spiced with salt, pepper and thickened with cereal. Served in either a sausage or in slices usually with fried potatoes and bacon. Tastes exactly the same as Scottish haggis.

Could also be pfälzer saumagen in the south.
