This is a bohemian side dish.
Usually serves with gulash but goes really well with any kind of stew.
You use cubed dried white bread rolls and eggs and milk and butter and then shape it together in a cloth napkin and cook that.
You can slice it and fry it a little to make the slices crunchy.
How is it fried? Looks interesting.
You wrap the whole thing in a cloth and close it up with thread like a bonbon and Cook that cloth.
Then you slice it and fry the slices in oil or butter
I’ll take progress pics the next time I do one. But there’s a lot of recipes if you look for “serviettenknödel”
