Stuffing cooked inside the turkey is really delicious, but it does slow down the cooking time. It can also be a potential health hazard if done incorrectly. If you are worried you won't get it right, cook your stuffing on the stovetop. Instead of stuffing the turkey, sauté everything, then cover and let it simmer. Add a little stock every once in a while; you need to have enough liquid for the rice to cook.
