Two days ago, as the Belgian son of a German mother, I tried to make Grüne Klöße, a German potato dish, created from grated (?) potatoes. The potato flakes get squeezed, in order to get the water out, the resulting potato flakes become a dough, which gets formed into balls and those get cooked in a very gentle way: even experienced Klöße-cookers sometimes end up with potato soup :-)
As I'm a complete newbie, I also ended up with a mess and in future, I would like to avoid this. In supermarkets in Germany, it's possible to buy prepared Klöße, which are packed in a kind of paper bags, preventing the potato flakes from getting loose and ruining the dish.
I would like to buy such paper bags (although I believe other material, like cotton might be better suited), I could search for these on bol.com (or any other e-commerce platform) but I have no idea how those bags are called, not in English nor in Dutch (my mother tongue).
Does anybody have an idea where I might find such Klöße-bags?
Beware: at the beginning of the preparation process, the grated potato flakes must be squeezed in order to get the moisture out of it. For that I use a regular kitchen towel, so this is not what I'm talking about: I'm specifically looking for the small bags in which the individual Klöße are to be cooked.
