Beets are often described as having a sweet, earthy flavor, which is a euphemistic way of saying that their taste is unique and polarizing.
If you like beets, great; please keep reading. If you don't, great; there is absolutely nothing I or anyone else can say to change your mind.
There are many decent ways to serve beets, and all of them require staining your hands fuchsia. If you want to serve them sliced in a salad, you can wrap them in foil and bake them. This makes them easier to peel, but it also makes them more prone to gush juice all over your countertop.
The alternative -- peeling them before you cook them -- will turn the space between your fingernails and your fingertips maroon for days, but it is fairly straightforward, assuming your vegetable peeler is adequately sharp.
