I am pretty sure most countries have some version of it :)
It is very basic and normally after it is fermented we prepare other dishes based on it. Eater way a soup, or something like a stew (bigos) or make a salad (just add some chopped apple, onion, olive oil and back pepper - delish!). We even stuff dumplings or crepes (krokiety) with it after mixing with some mushrooms or meat. Soooo many ways to eat it!

You're very welcome :)
