Sizzlin saw it too. They plated a dish with a clear glass cover over it (kind of like a layer cake cover). Then he used some sort of hand held smoke maker to fog up under the lid and to let the smoke permiate the food. Even Alton said it looked like a bong.
Unfort., the only part I saw of the show was the judging and thats when I saw it. Your sure it wasn't just a glass covered cheese board that he turned into a smoker? Thats sure what it looked like to me.
Se non supporta il calore, vattene dalla cucina!
