I don't know of any other use than just to eat it. Of course there'd be various ways to combine it with other foods - sauerkraut on top of a sandwich, or together with a warm dish. Well, at the moment I'm pretty low on money, so I try to minimize buying food from the supermarket. And I still have a good supply of potatoes from the last harvest, so looks like my main diet will consist of potatoes (steamed or fried) and sauerkraut until either of them runs out of their shelf life =)

Last autumn my neighbour happened to get a big load of excess cabbage, and to preserve it they made as much of sauerkraut as they could. So now there is plenty of it. I'd love to grow cabbage of my own, but haven't yet learnt the best ways of doing it; every time I try, the pests eat the saplings before they get to grow stronger. And for this growing season it looks like indie coding is going to take a lot of my time and attention, so with my gardening I will go with scaled down minimal effort approach.
