This take on the traditional Beef Brisket, often served during Jewish holidays, is based on a variety of cherished family recipes. The Brisket gets slow-roasted over a bed of caramelized onions and garlic in beef broth for a luscious braise that is simple and satisfying. The onions and pan juices turn into a smooth sauce with the help of a blender, that is finished with a splash of cider vinegar. We think this recipe would make any Bubbe (Jewish grandmother) proud!
