Norman - I've never deep fried a turkey but from what I've read doing a quick Google search, a lot of people do it. Below is a comment from one of the sites I visited. I will list the link below it. You probably already know this but hot grease and water don't mix well so keep safety first! Here's the info from the site:
"I know sounds a little kinky! What more can a turkey want?I brined, injected, rubbed, and deep fried this turkey for the Fourth of July. This is a quick way to cook a turkey. I had a 14 pound turkey cooked in 35 minutes. All in the time is in the prep. Make sure to remove plastic leg holder and pop up timer. Giblets and neck can be used for an other use(Stock).I gave this 15 hours of passive work time. Brining is good at 10 hours. Take note the turkey looks burnt but its not its all the rub and being deep fried. Everyone picks at the crispy skin. It`s wonderful. � Jul 8, 2004"
