I dont actually buy turkey either, Its far too big for my oven at christmas, so i have a large chicken instead!! But no, i believe everyone i know makes and bakes their stuffing separately from their meat.
Nitpick time: it's not stuffing if it isn't in the turkey. If it isn't, it's "dressing". Sure, you can eat it, but they recommend a higher internal temperature if cooked that way, followed by rapid removal the instant the turkey ;eaves the oven. You can call the Butterball hotline for information on that. Seriously! My family once had to cook a turkey in advance to take to my aunt's house (my uncle was near the end and we wanted her to have some sort of Christmas without leaving him), and they told us how to bake it in advance, then slice it and layer it with gravy in a saucepan for re-heating when we got there. Wow! It worked! Everything was tender and juicy and delicious!
Yes! Stuffing it inside the turkey makes it stuffing, while keeping it separate makes it dressing. The flavor changes, and yes -- health risks do too. Inside, you absorb a lot of the turkey flavor and add moisture, while outside it is a little more dry and keeps the taste of the main ingredients (the breads, vegetables, et cetera). But as I said, the cooking temperature can easily remedy the concerns. Just remove stuffing from the bird immediately, before it can cool, and the salmonella threat is largely eliminated. Wow, you can't get them there? Here, stores give them away free with enough groceries. You accumulate points for a few weeks, and that earns the right to a free turkey. Decent-sized one, too!
