Once the water is boiling, remove from the heat and place the Weisswurst in the water. The sausages should gently be warmed up. Do not place a lid on the saucepan. The ideal water temperature is about 70°C/158°F.
To serve them the traditional way you place them in pairs in a terrine with some of the cooking water. Serve them with some sweet mustard, a pretzel, and a glass of cold wheat beer.
Notes
How to eat Weisswurst
Zuzeln - like a Bavarian
To eat the Weisswurst like a Bavarian, you hold it between two fingers. On one end, you bite an opening into the casing.
If you like you can dunk it into some sweet mustard(affiliate link).
Suck the meat out of the casing.
Once you reach the halfway mark of the sausage you can either peel the remaining casing off or turn it around and start again.
With Knife and Fork - the Banana Method
If you prefer eating with a knife and fork, you use can make a lengthwise incision into the sausage. With the fork, you can fold away and remove the casing.
