For the Turkey Osso Bucco: Preheat the oven to 375 degrees F. Pat the turkey with paper towels to dry and ensure even browning. Season the turkey with salt and pepper. Dredge
the turkey in the flour to coat.
In a heavy roasting pan large enough to fit the turkey in a single layer, heat the oil over medium heat. Add the turkey and cook until brown on both sides, about 6 minutes per side. Transfer the turkey to a plate and reserve.
In the same pan, add the onion
, and celery. Season vegetables with salt. Cook until the vegetables are tender, about 6 minutes. Stir in the tomato paste
and cook for 1 minute. Stir in the wine
until the liquid is reduced by half, about 3 minutes. Return the turkey to the pan. Add enough chicken broth to come 2/3 up the sides of the turkey. Add the herb sprigs, bay leaf
, and cloves to the broth mixture. Bring the liquid to a boil over medium-high heat. Remove the pan from the heat. Cover the pan tightly with foil and transfer to the oven. Braise
until the turkey
is fork-tender, turning the turkey after 1 hour.

, garlic, minced rosemary, and a pinch of salt and freshly ground black pepper in a bowl. Cover and reserve until serving the turkey.
