Abstract:
1. A commercial method of frying discrete batches of food comprising: extending a life of cooking vat oil, wherein batches are successively cooked during a period of time required to achieve an oil turnover and for an extended period of time thereafter without changing the oil and without sacrificing quality of the cooked products; providing a fry vat containing an amount of cooking oil; separately and sequentially cooking, in the cooking oil one or more discrete batches of uncooked food at a time, the weight of the amount of food in each discrete batch on a weight basis relative to the weight of the amount of cooking oil being in the range of from about 0.0375 to about 0.1, wherein the weight of the total amount of food being cooked in the fry vat at any time relative to the weight of the amount of oil in the fry vat being less than or equal to about 0.1, where the food being cooked in the batches is uptaking oil in an amount of from about 5.5% to about 13% by weight of the uncooked food at an oil turnover ratio of the amount of oil uptake by the food in each discrete batch to the amount of oil in the fry vat on a weight basis being in the range of from about 0.0026 to about 0.007 per discrete batch; removing each discrete batch from the fry vat after cooking; adding replacement oil to the fry vat to replace the uptake oil of the food; sequentially cooking a sufficient number of the batches until the oil turnover is equal to the amount of oil in the vat in a period of less than about 60 hours of operation of the fry vat.
