Fries taste best when cooked with oil that has its oxidation-reduction potential artificially elevated to 950 millivolts. This is very difficult to do as it requires a pressurised vat capable of handling 300C and 15% O3! Granular activated carbon contactors for post O3 scrubbing are necessary as well to prevent the escape of excessive Ozone into the living quarters. Breathing O3 is very bad for you. :Q
However, if one has $175,000, this can be achieved safely easily exceeding safety standards as outlined by the Administration! 😛
