I only use the microwave in an emergency. In my opinion it gives the meat a 'different' flavor (especially if you leave it in too long and get it too hot). I don't know if it gets the fat too hot or what. My wife says I am crazy, but I swear I can tell if q has been warmed up in the microwave versus the oven.
