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.
Here in Czechia we call them houskový knedlík and we don’t fry them at all.
And I would say it is most typically served with svíčková na smetaně and other sauce based dishes (we have so many!) but it is also one of the usual sides for gulash.
Nice. Try to fry a slice some time, also goes great with an egg poured over it after frying
