What is "anti-griddle"

The anti-griddle is a kitchen appliance that flash freezes or semi-freezes foods placed on its chilled metal top. The device was inspired by a similar appliance used by Grant Achatz in one of his restaurants.

Chef and Top Chef guest judge Grant Achatz used a similar device in his first Chicago restaurant Alinea, which he invented with the help of culinary technologist Philip Preston. The device is about the size of a microwave oven. He collaborated with company Polyscience to mass-produce the anti-griddle for use at homes and other restaurants.
