One day, I'd like to do a direct taste-comparison of chips fried in different things. Lots of people talk about how chips fried in lard are way better than those fried in oil. I'm aware that sometimes you get good chips, bad chips and better chips but have never managed to correlate it to what they're fried in. My non-meat-eating friends tell me that Whitby chip shops tend to use lard, and you do get good chips in Whitby, but I don't know if those facts are related.

Obviously you can have good chips-in-oil, and bad chips-in-lard, but I want carefully controlled identically-processed chips in oil and lard so I can compare. I have no idea how to achieve this :)
