Vitelotte potatoes are small to medium in size and are elongated and slender, similar to a fingerling potato, and are cylindrical with irregular lumps. The smooth skin ranges from dark purple to deep violet-blue and is speckled with deep-set eyes giving it a bumpy texture. The flesh is smooth, firm, and dense and has a deep purple hue that is occasionally marbled with white. When cooked, Vitelotte potatoes retain their vibrant hue and offer a dry, floury flesh with nuances of chestnuts.
Vitelotte potatoes are best suited for cooked applications such as boiling, steaming, baking, and frying. Used on their own or along with other potatoes, they make for an excellent potato mash. Unlike some other purple-hued vegetables, Vitelotte potatoes will retain their purple color even when cooked and are best showcased in potato salads or a roast of tubers. Vitelotte potatoes can be cooked and pureed to make purple-hued soups and sauces or fried to make purple chips and crisps. Their dry texture also makes them ideal for making potato pancakes. Vitelotte potatoes pair well with garlic, beets, watercress, parsley, cherry tomatoes, avocado, olive oil, white pepper, blue cheese, and balsamic vinegar.
They will keep up to three weeks when stored in a cool, dry, and dark place away from moisture and refrigeration.
