Purple potatoes vary in size and shape, depending on the variety and growing environment, but are generally sold in commercial markets when they are 7 to 15 centimeters in length. The tubers range in appearance from oblong to round and can be uniform or lumpy in nature, exhibiting indentations across the surface. The skin is thin to semi-thick, taut, and hard, either smooth or russeted, depending on the variety. The surface also contains a few to many eyes that can be shallow, moderate, or deep-set. Purple potatoes are found in unique shades of saturated royal purples, violets, blue-purple, to dark purple, almost black. Underneath the surface, the flesh is dense, starchy, and firm, also revealing brilliant shades of solid purple to marbled purple, red, and white hues. Purple potatoes are only edible once cooked and hold their shape well. Each variety will have its own blend of flavors, but the tubers usually have a rich, deep, and earthy taste with sweet and nutty nuances.
