I was a short order cook in a former life, and have always loved cooking on the plancha. After spending Christmas week at my inlaws cooking on the griddle top on their indoor range, I've started down the rabbit hole. My current setup is a Weber Genesis 330 NG and large BGE. Have considered the little griddle, and the griddlemaster pro insert. Little griddle grease management seems stupid. Griddlemaster grease managment is non-existent. I would lean towards the griddlemaster and just leave it in the Weber in place of the grates, but the only way to clean the grease is scoop it up with a spatula? There's a video on their youtube where the dude cooks a bunch of bacon and then spends a minute scooping burning hot bacon grease into a stainless mixing bowl. Ain't nobody got time for that. Plus, the price of a griddlemaster is perilously close to a 36" blackstone without any accessories. One way or the other, this is bound to happen
DDD - what did you wind up doing?
