Roast Beets with Wine Vinegar, Butter, and Parsley

Because beets take a long time to roast—about an hour— it is worthwhile to roast more than you need and then serve some of them cold in salads or as part of a crudité plate later in the week. Beets are great with vinegar, especially wine vinegar with a full woody flavor, such as sherry vinegar, good balsamic vinegar, or homemade vinegar.
