I don’t know, if it’s more popular in other regions of Germany, but I’ve only had plain sauerkraut once in my life. 🙃

Only real dish involving sauerkraut around here is Krautschupfnudeln:

And well, by roasting the sauerkraut, it caramelizes a little bit and some of the vinegar dissipates, so it doesn’t actually taste as sauer anymore.
