Double-Bone Beef with Red Wine Sauce

For any bone lover, what could be better than two bones—rib and marrow—in one dish? A standing rib roast is great for a crowd but impractical for two people. This recipe is the perfect way to enjoy a rib of beef without buying the whole roast. Begin this recipe a day in advance, as the marrow bones must be soaked to remove the blood. You can make the sauce ahead of time and reheat it while the beef is cooking.
