Pierre Schaedelin's Braised Short Ribs with Celery Root Puree

Combine ribs, wine, garlic, leeks, and carrots in a large roasting pan. Cover and let marinate in the refrigerator 1 day.

Remove rib sections from marinade and pat dry, then season all over with salt and pepper. With a slotted spoon, transfer vegetables to a colander; reserve marinade.

Heat olive oil in a large saute pan over medium-high. Sear two rib sections at a time on the meat side until browned, then transfer to a large pot. Once all ribs have been seared, pour off all but 2 tablespoons fat from pan and add vegetables to pan. Saute until deep golden brown, stirring occasionally, about 8 minutes. Transfer to pot and add reserved marinade and the stock. If necessary, add enough water to just cover ribs and vegetables. Bring to a boil, then reduce heat and simmer, covered, until meat is very tender but is not yet falling apart, about 1 1/2 hours.

Using tongs, transfer ribs to a rimmed baking sheet. Strain liquid through a fine sieve into a saucepan; discard solids. Bring liquid to a simmer; cook, skimming off foam and impurities from the surface, until reduced to 2 cups, about 1 hour. Skim off fat, then stir in chocolate until melted.

In a small bowl, stir together 2 tablespoons water and flour, then whisk into sauce. Simmer, whisking, until sauce thickens, about 2 minutes. Strain sauce through a fine sieve into a clean saucepan.

Remove bones and membrane covering underside of ribs. Trim away excess fat. Arrange ribs in a single layer in bottom of pot. Bring sauce to a simmer, then pour over ribs. Bring to a boil. Reduce heat and simmer, covered, until meat is heated through, about 5 minutes. Serve hot with celery root puree, Chinese long beans, and braised salsify.
