Beets. People either love 'em or hate 'em. Personally, I love them, and think that most people who claim to hate them have only had flabby, flavorless slabs from a tin can. Fresh beets are sweet and have a complex, earthy flavor and satisfying, almost waxy texture.
They're one of a handful of vegetables available all year 'round here, but since so many other things are out of season at the moment, perhaps they've caught your eye. Now's a good time to buy a bunch or 10 and put some up for later.
You could just can them straight up. But note that, like most vegetables, beets are a low-acid food, and so cannot be canned by the water-bath method without acidification. So if it's just beets you want, make sure you've got a pressure canner.
So what are you waiting for? Get out there and beet it!
