Deep frying - taste difference in saturated vs. unsaturated oil In one of my questions I received answers that indicated using more saturated (Animal) fats would extend the life of my deep frying oil.

However - given proper maintenance / cleaning / good oil - how can the taste difference between fries made in saturated vs unsaturated oil be described?

(I use fries in the question as they are fairly neutral in flavor).
Fries cooked in animal fat will taste distinctly different than those fried in a neutral vegetable oil. They will be much richer in flavor and may make you weep with joy.

If you haven't had them, you must stop what you're doing and make some duck fat fries.

Here is a good recipe: http://hecooksshecooks.net/2009/03/duck-fat-french-fries/
