Abstract
Abstract An auxiliary fat container near a deep fat fryer lowers to a convenient height for filling with an entire replenishment package of solidified cooking fat. A heater within the auxiliary container melts and elevates the temperature of the replenishment fat to approximately cooking temperature. A fat level sensor within the deep fat fryer meters the addition of preheated replenishment fat.
