Btw if you haven't seen this guy before, he's a Ukrainian youtuber called super sus and he does some interesting urban exploration. Not as much old soviet stuff these days for some reason but still going.
I live in Norway and would make the case that everything we grow outside is like this. Potatoes, beets, carrots, cauliflower and onions are the most popular crops.
I mean, you say that, but I once had some carrots which had turned black on the outside and when I peeled them, they still looked and tasted like fresh carrots.
