Yes, I've tried several different coatings- like cajon seasonings, even Jerk Chicken coating, but just plain ole flour works great! Keep the skin on!
You do not have to inject legs or wings like you have to inject Turkey breasts when you deep fry whole tukeys in those outdoor turkey fryers.
Mine always turns out tender- well it is a turkey leg! They are a chore to eat- but a well worth chore!
Be sure to always use a food thermometer- when it is 165 degrees all the way to the bone- they are just about ready!
For whole turkeys, I just spatchcock them and do them on my Traeger. Always great.
