Russets are best for frying They have a high starch content and relatively mild flavor. Look for Burbank russets, which develop a crisper texture and cook more evenly than Norkotah russets. If the variety isn’t indicated on the bag (or if you’re buying from a bulk bin), try asking the produce manager which variety is typically stocked. Russets may also be labeled as Idaho or baking potatoes.
Soaking removes excess starch Letting the sliced potatoes soak in water and then rinsing them a few times removes excess surface starch, which would otherwise cause premature browning when the potatoes are fried.
A neutral-flavored oil produces fresh-tasting fries Peanut and canola oils work best. They also have a high smoke point, which means they can reach the high temperatures necessary for deep frying without burning.
The ultimate texture comes from double frying The first fry (at 330°F) softens and cooks the potatoes through; the second fry (at 360°F) browns them to crispy perfection. Frying the potatoes just once produces tough, grainy, cardboard-like results.
