Abstract: A frying oil system (100) generally includes a frying vat (108A) having a frying oil contained therein. The frying vat (108A) can be supplied by two or more oil reservoirs (104A, 104N), such as to establish a desired oil blend of different oils from the two or more oil reservoirs (104A, 104N). A sensor (124A) can be used to provide data indicative of a characteristic of in the frying vat (108A). Establishing the blend can include automatic control taking into account data obtained from a sensor configured to receive sensing information relating to one or more attributes of the frying oil in the frying vat (108A).
