Sauerkraut

The problem with that is there are two types of it - the sweet one and the sour one. In a restaurant you'll usually get the sweet one which I think is tastes awful.

But the sour one is the really good one especially if you refine it by adding fine cubes of Kassler (smoked pork chop) to enhance the taste. Sour Sauerkraut should even change the taste of potatoes that sit in its... sauce? broth? (don't know the word). I could eat kilos of it.
You'll need to look out for the right kind of Sauerkraut in the supermarket. Not everyone of them is suited for this.

I'm in Germany and people rave about their bread but I live in Mannheim and it's like... Okay? I don't have a bakery here that I like more than the ones in New York (specifically) or France (seemingly anywhere) or Vietnam or Japan.

Maybe it's because I haven't found how to use them properly but there just doesn't seem to be a large amount of diversity. Like I'd expect fresh made hamburger buns, the Bahn mi bread, like a good sub situation, fresh rye bread, idk. Also for a country to have good bread I need to be able to walk into any corner bakery and be satisfied 4/5 times.
