The anti-griddle is a kitchen appliance that flash freezes or semi-freezes foods placed on its chilled metal top. [1] [2] The equipment is about the size of a microwave oven.
Chef and Top Chef guest judge Grant Achatz developed the device with Philip Preston [3] for use in his Chicago restaurant Alinea. [4] He collaborated with the company Polyscience to mass-produce the anti-griddle for use at homes and other restaurants. [5]
The anti-griddle maintains a constant temperature of −30 °F (−34 °C) by pumping a refrigerant through a compressor to remove heat from its steel surface. [6] Liquids, oil, and gels generally freeze in 30 to 90 seconds. The finished product has a crunchy outer texture while the inside remains soft or creamy.
