Brisket with Apricots and Prunes

Preheat the oven to 325°. Season the brisket with salt. In a large enameled cast-iron casserole, heat the olive oil. Add the brisket and cook over moderately high heat until browned all over, 4 to 5 minutes. Transfer to a large plate.

Add the onion to the casserole and cook over moderate heat, stirring occasionally, until softened, about 5 minutes. Add the thyme, garlic, tomato paste, paprika and cinnamon and cook, stirring, until the tomato paste is deep red in color, 1 to 2 minutes. Add the tomatoes and chicken stock and bring to a boil. Remove from the heat and stir in the prunes and apricots. Return the brisket and its juices to the casserole. 

Scrunch up a large piece of parchment paper and moisten it with water. Spread the wet parchment over the brisket, cover and braise in the oven until tender, about 3 hours. Transfer to a work surface and let rest for 10 minutes. Discard the thyme sprigs. Slice the brisket across the grain and serve with the sauce.
