Mandoline-cut sweet potatoes fried in rendered duck fat then sprinkled with coarse salt and freshly-ground pepper..
Salt and Pepper Sweet Potato Chips frying in Duck Fat
Wash and peel as many sweet potatoes (garnet yams) as you intend to fry. Using a mandoline set to about 1/16″, slice potatoes on a bias directly into a bowl of ice water. Allow potatoes to sit in ice water for 1 hour, then spread out on clean kitchen towels and pat completely dry.
Heat rendered duck fat (substitute beef tallow) in a scrupulously-clean skillet to a depth of about 1/2 inch until it shimmers. On my electric stove, I set the dial to mark below medium. If the oil is smoking, the pan is too hot.
