My missus has been making home made sauerkraut of late. Made with red cabbage, caraway seeds and sometimes cardamom. It's bloody good stuff. Smells a bit "farty" while it being made and fermenting but results are top notch. A lovely crunch and goes brilliantly with cooked meats.
As a bonus it seems that the wonderful nutritional benefits of fermented foods for our "gut biome" are only now becoming better understood in the mainstream.
I remember reading that the German navy was able to stay at sea longer than the Brit's because they carried sauerkraut on board which staved off scurvy. It provided vitamin C which was otherwise largely missing from ship's rations after several weeks at sea. Dunno if that's true or not.
Edit: I don't really understand if "pickling" = fermented ingredients or not? Some pickling just seems to be veg or whatever in vinegar.
