Grant Achatz has made the use of pure scents – complementing the taste of food with items used for their smells alone – a hallmark of his inventive cuisine. "This year, for instance, rosemary branches began appearing on Alinea’s tables as centerpieces, only to become aromatics when, midway through the meal, they were placed into holes in the restaurant’s specially designed terra-cotta serving pieces, which were heated to 400 degrees." When I ate there last spring, I was served black cod on a pillow that released the scent of orange as it deflated. It was spectacular.
