[QUOTE 2821954, member: 259"]Ignore all previous advice and double cook in beef dripping.

[/quote]
As the chipmeister in our shared student house in the late seventies - at my peak I'd despatch 3 stones of potatoes per week through the chip pan and having tested for several weeks at a time:
Lard
Beef dripping
Corn oil
Vegetable oil
I can assure you that there is no real difference in the flavour of the chips until the fat or oil starts to oxidise. Chips produced with fresh oils or fats are all great tasting. An superiority in taste is imaginary or wishful thinking. My house mates still talk wishfully about the fry-ins thirty five years later.
Addendum. I flatly refused to cook chips when arriving home from the pub not so much that I was worried about falling asleep but that I'd get distracted by the music and narcotics elsewhere in the house. I was easily led astray.
