Beets are in season; citrus is in season. Might as well use them both to advantage.
While the term "glazed beets" might bring up images of those horrendous color photographs that used to appear in cookbooks back in the 1950s and 60s, don't be put off. If you like beets, this is a great recipe. Cooking the beets in citrus juice and then reducing the juice into a sweet, tangy sauce rich with butter is just about one of the nicest things you can do to a beet.
Admittedly, this is a very rough recipe, only because I've never bothered to measure it out. It always works and - despite the peeling and slicing of the beets - it's very simple. You could always squeeze your own citrus juices, as well, and it does taste better but I won't hold you to it. Don't, however, leave out the grapefruit juice. I don't like grapefruit juice by itself, but here it adds a depth to the citrus sauce that pretty much makes the dish. If the juice reduces too quickly before the beets are tender, just add water or a little more juice.
