Within the commercial frying oil series (Fryplus) of Pakplast, we have a special commercial chip frying oil – ALLL-FRY. This is a specially formulated oil best for chip frying and it is used by many fastfood stores in which a lot of crispy chips are prepared.
The key here is using something with a high smoke point. Neutral-tasting oils are great for frying: peanut, canola, vegetable, safflower, grape-seed, et cetera. These all have a smoke point well above 350°F. Some oils, like corn, coconut and sesame, have smoke points beyond 350°F, but they impart a lot of flavor into the finished product that you may or may not want. And olive oil or anything unrefined has too low a smoke point to be useful for frying, as it will burn before it hits the temperature that gets you a golden-brown exterior….
