Flip em’ upside down and you’ll produce an amazing all over “griddle” sear. I think that one of the things that sets these apart for that all over sear is the holes. The grease drips through the holes keeping the griddle surface a bit drier than a normal solid griddle surface. From my experience, this just increased the Maillard reaction
Here’s a pic of a simple burger cook I did awhile back...
Another bonus that you get with GrillGrates is that you can cook over the charcoal fire for the entire duration of the cook when grilling. Being that GrillGrates have holes that allow the drippings to fall through and hit the fire... this simply means that you are getting the additional flavoring from all of those flavor bombs hitting the fire the entire time you are cooking vs much less time with a 2 zone cook
