I have found that in order to get and keep a griddle hot it needs to be directly over flames. In a Q this means dedicated half round or oval griddle and pulling off the grate to use. On a grill with flavorizer bars, they need to come out. I found it greasy and troublesome to do that each time I used the griddle so I went with a the Razor as a dedicated folding griddle. After doing many smash burgers, I am back to thicker ones as I like them medium and pink in the middle. I do them charcoal, griddle, or hot grill. I did see White Castle molds and kind of want to try that for fun some time.
