I suspect North Americans might instinctively shy away from these things on account of their appearance, but for me, they rank among Germany's loveliest treats. The video linked to in the link below refers to them as "Munich" sausages and "Bavarian" sausages. But they can be found elsewhere around the country as well, sometimes with variations in size, recipe, and manner of preparation. I made a lunch of these recently at a tavern in Mainz (around 5 driving hours from Munich) which were prepared and served just as you see them in this video. Elsewhere, I've had larger ones that were grilled as well - which I prefer personally. Nothing like these when you're hungry! Another member posted this on the food-and-drink forum about 3 months ago, but I thought those of us who frequent the Germany forum might have missed it.
