Do you still not get ash on the steak whilst it's cooking?
A little bit yes, you’ll also get little bits of charcoal stuck to it, so it can be a bit gritty. I do enjoy a dirty steak, but only once in a while.
I think it’s more of a trendy thing that looks better in pictures. Cooking in a pan/on a bbq is much more consistent and less hassle, and the grittiness isn’t especially pleasant. The flavour is nice, though.
