First, let me start by clarifying that I do love my Memphis Pro. I'm just looking for tips and ideas to be able to reverse sear beef without tossing a coin on the odds of starting a grease fire.
I've had my grill for less than a year and think I've had 6 grease fires now. Two on Prime Rib (4-5 pounders), two on chuck roasts at medium cooking temps like 325 or 350, others doing steaks. I don't clean my pit to Trooper's described detail, but before I start a fatty beef cook, I always make sure the grill is scraped down and there's no grease in the catch pans. Though on at least two of the fires I had just finished a burn off, scrape down, vacuuming out and drip tray change right before starting the cook (so it was Trooper clean). Essentially, the grease from the cook I'm doing is starting the fire. I usually start at 200-250 until a temp of 120, then try to turn up the grill to 500 until meat gets to 135 (we like medium).
I've had fires on the drip tray and in grease pans. I love to reverse sear Prime Rib and steak, so would like to hear others methods to do this without having a fire and ruining our dinner or my grill. I've even tried GrillGrates (I had some already from a past grill that ended up being full fit for my Pro). I used those on my last Prime Rib, thinking that another layer between the Fire and the meat might help. That ended up causing a fire on the GrillGrates instead of lower in the grill and charred the xxxx out of my ribeye roast even though I was right there and removed it pretty quickly.
The one thing I have not yet tried is cooking on the middle shelf with a pan under the meat on the main grate so I can remove that pan when I turn up the heat. I'm not totally opposed to this, but if there are any other ways that don't take away cooking space I'd love ideas to try.
