Balsamic-Braised Short Ribs with Horseradish Mashed Potatoes
Short ribs are the meaty ends of the rib bones. Choose cuts from the chuck, which are the most flavorful, or from the rib, which are a bit leaner. Packages labeled "short ribs" in the supermarket are likely to come from the chuck. Start this recipe a day ahead. It will taste much better, and chilling the ribs in the cooking liquid will make the solidified fat easy to remove.
