Le Bonnotte is the world's most expensive potato, grown on the Île de Noirmoutier, an island in the Bay of Biscay. These rare potatoes grow in sandy soil that absorbs the ocean scent and is fertilized with seaweed and algae. The land space on which the potatoes grow is limited to less than 50 square meters.
The fragile and delicate Bonnottes are picked exclusively by hand, one by one, during only one week per year, which explains the high price of 500 Euros per kilogram. They shouldn't be peeled, as the skin absorbs all of the aromas and flavors of the soil and the nearby seawater.
