The "anti-griddle" is a super-chilled slab of metal in your kitchen that nearly instantaneously freezes anything you set down on it:
* Quickly freezes sauces and purees into solid, unique forms – or freezes just the outer surfaces while maintaining a creamy center.
* Minus 30°F 'griddle' temperature ensures almost instantaneous results.
* Approximately 1 square foot high-endurance cooktop provides an ample, easy-to-clean work surface.
