Pasta Ribbons with Shredded Beef Brisket

Put oven rack in lower third of oven and preheat oven to 325°F. Pat brisket dry and sprinkle with salt and pepper. Heat 1 tablespoon oil in a 6-quart heavy pot over moderately high heat until hot but not smoking, then add brisket and brown on both sides, about 12 minutes total.

Cut carrots, celery, and onions into 1-inch pieces, then pulse in 2 batches in a food processor until finely chopped.

Transfer brisket to a platter. Add 1 tablespoon oil and chopped vegetables to pot, then sauté over moderately high heat, stirring, until softened and golden, about 5 minutes. Add wine, stock, tomatoes, bay leaves, and 7 whole garlic cloves and bring to a boil. Return brisket with any juices on platter to pot and cover, then transfer to oven. Braise brisket, turning over once per hour, until tender enough to shred with a fork, about 3 hours. Transfer to a cutting board and cut into 2-inch chunks, then shred with 2 forks. Discard bay leaves from sauce and purée sauce in 2 batches in food processor or a blender (use caution when blending hot liquids).

Mince remaining garlic clove. Heat remaining tablespoon oil in cleaned pot over moderately high heat until hot but not smoking, then sauté garlic, stirring, 1 minute. Add meat and sauté, stirring occasionally, 5 minutes. Stir in sauce and season with salt and pepper.

Cook pappardelle in a 6-quart pot of boiling salted water until al dente. Drain, then return to pot and add meat sauce.
