We plugged our energy meter into a mains socket then plugged our thermostatically-controlled deep fat fryer into it. We had already entered our electricity price into the meter so it could give us a direct readout of running cost. The fryer was switched on to warm up to 190 degrees, which took around ten minutes. It was then used to fry two portions of chips (french fries).
