I own one of those beautiful cast iron grill/griddle combos. Have for a long time. But, and here's the rub - I never use the grill side any more. Because after I use the grill side, when I flip it over and use the griddle side, all the crap that has formed on the grill side is now exposed to two gas flames and basically burns off flooding my apartment with smoke. Am I doing something wrong...because I if am, I can't figure out what it is. And therefore, isn't this a pretty useless piece of equipment? Well, other than using only 1 of the sides. Or using it outside. Or using it with a giant ventilation hood, which I don't have.
