There are several ways of eating Weisswurst. The most common techniques are:
Zuzeln
First slicing, then peeling
Ripping and slicing
Zuzeln is the only way of eating Weisswurst that has a special name - the other methods have no explicit name.
All techniques result from the fact that you normally do not eat the peel of the Weisswurst. Of course you won't die if you eat the skin anyway, but it is not common practice.
Zuzeln
Zuzeln is a term in Bavarian slang and means sucking. The technique is as follows; the first half of the Weisswurst filling is sucked through one open end of the Weisswurst. After that, the rest of the Weisswurst filling is sucked through the other open end. You may notice that in order for this technique to succeed, the Weisswurst must be open at both ends. Therefore you have to cut off the knots and metal clips that may sit on the ends of the sausage before starting to suck. You should also notice that you use your hands for this technique - don't even try to work it out with a knife and a fork.
You should be warned that Zuzeln is the most complicated technique. If you are not trained to eat your Weisswurst this way, it might end in a mess. It is an art to use this technique without disgusting the other guests.
First you should probably watch this technique several times before applying it yourself. For your initial tries you should especially be careful with your teeth, since the Weisswurst peel is very delicate. If the peel becomes perforated by your teeth, sucking will become impossible. The second thing that is very hard to accomplish is the elegant handling of the empty Weisswurst half when starting to suck at the second end. Since the empty half looks like a condom - which is not very appetizing - you should cover it with the palm of you hand. The same applies if you have finished eating the whole Weisswurst. Then you should try to elegantly put the peel on the plate without dangling it around.
First Slicing, then Peeling
This is an easier technique for eating Weisswurst. First you have to cut your Weisswurst in slices of about one or two centimetres in thickness. After that the trickier part starts. You have to remove the peel from each of the slices. If you are skilled in handling a knife and fork this will be not so hard - for children it might be much harder. After that you just eat the slices.
Ripping and Slicing
This is the easiest, but also the most brutal technique. First you rip the Weisswurst along one side. Then you remove the peel, and finally you slice the sausage and eat the slices.
Conclusion
As you can see, eating Weisswurst is in fact an art. But don't be shy - just try it - it's worth it. Weisswurst is a real delicacy."
