Flipping your GrillGrates over and cooking on the back side or flip side has really gained a lot of momentum in the past few years.

Grilling on the flip side can also allow you more of a “griddle” type of cook for peppers, mushrooms, onions, you name it. GrillGrates are two cooking surfaces in one.
