To serve the confited turkey legs on Thanksgiving Day, preheat the oven to 350°. Gently rewarm the turkey legs in the large pot over moderate heat, just until the fat melts. Remove the legs from the fat and transfer them to a roasting pan; reserve 2 tablespoons of the fat. Roast the turkey legs for 25 minutes, turning once or twice, or until golden and crisp in spots. Transfer the turkey legs to a platter, cover loosely with aluminum foil and keep warm.
