GrillGrates are a must for your grill or smoker. Seems like every pro uses them!
They are thick rails, on an aluminum base, that you can lay over part of your existing grates (or order them made to fit many popular grills). The aluminum conducts heat extremely well, so the rails will heat up to way over 600 degrees, to give you those perfect sear lines. And the aluminum baseplate works to minimize flare-up from dripping fat. You can also reverse the grates to flat side up and use like a griddle, or for a flat sear. They come in interlocking sections (purchase at least a set of two sections) and can include a special spatula that fits in between the rails for easy lifting of your food. Shop the net for best pricing.
