When you think about expensive food, potatoes aren’t exactly the first ingredients that come to mind, are they? Believe it or not La Bonnotte potatoes are one of the world’s most expensive foods, served only in the most luxurious restaurants.

The price of one kilogram of La Bonnotte potatoes can reach $700, making it the most expensive potato on Earth. Its ridiculous price doesn’t just have to do with its delicious salty flavor, but also with the fact that it’s very rare. This variety of potato is only cultivated on Noirmoutier, an island off the coast of western France, and just 100 tons are produced every year, mainly because they have to be picked by hand. La Bonnotte’s tuber remains attached to the stem making too fragile to harvest by machine, not to mention it also needs to be fertilized with algae and seaweed to give it that distinct earthy, salty flavor. Its fragile nature simply didn’t make it profitable enough for large agricultural companies, and it was only because of teh love and care of a few French potato lovers that it didn’t go extinct.

Also known as The King of Potatoes, La Bonnotte is planted in February and ready to be picked in the first week of May. The entire crop is usually exhausted by the first weekend of the month, because they retain all of their flavor if their picked and shipped to the restaurant the same day.

One of the rarest vegetables in the world, La Bonnotte are served in exclusive restaurants, as part of secret recipes prepared only by the most talented chefs.
