Katie Cavuto Boyle explains how to buy, store and cook these small, slender “finger-sized” potatoes. Fingerling potatoes range from two-to-four inches in length. They come in a wide range of skin and flesh colors – red, orange, purple, yellow and white – and most posses a firm, waxy texture. Pan-frying, such as with the USPB’s Pan Fried Fingerling Potatoes with Wild Mushroom Sauce recipe, enhances their robust flavor and showcases their wonderful nutty or buttery tastes. Or try a twist on a traditional by using fingerlings for a truly unique potato salad.
