Thou shall not try to fry a turkey that is still frozen.  It should be the most important commandment this Thanksgiving season.  That being said,  you know that someone is going to try it and start a fire.  Don't do it.

The oven will work just fine.  If you're using the turkey fryer make sure you follow the instructions to the letter.  Don't fry it on a wooden deck.  That may sound obvious, but if you know any fire fighters ask them.  They'll tell you many have tried and many have failed.

Have a happy and safe Thanksgiving Day.
