Hey NOW!!! I prefer propane simply because it's far more efficient, quicker and one doesn't have to replenish the coals. I HAVE learned how to make propane grill cook with a good smoke flavor. It takes a little bit and perhaps some reconfiguration. I DO ABSOLUTELY loathe these new propane grills with those "flame tamers" (metal pieces over the gas flame) The new grill I bought this past spring had those. It provided a lackluster flavor, at best. I reconfigured the grill, got some ceramic/ hickory embedded briquettes, a metal rack to install them on, and now it cooks with a decent flavor. I add in some wood chips if I want even better flavor.
Don't misunderstand - I don't have a dog in the propane vs. charcoal fight one way or the other. I like it all, no matter how it's grilled.
(I don't understand that no-you-can't-use-starter-fluid. As far as I can tell, that stuff burns off and then it's just coals and good eatin' afterward.
)
My whole point involved the Flay vs. Jack thing. As far as I'm concerned, Flay turned out the loser - every time.
