Papas arrugadas (wrinkly potatoes) is the signature dish of the Canary Islands. This incredibly simple specialty is made with whole, unpeeled potatoes that are thoroughly cleaned and then cooked in salted water. The dish was traditionally prepared with seawater, but nowadays, the water is usually just heavily salted.

When cooked, the potatoes are put in the same pot without the water. The process allows any additional moisture to evaporate, leaving the potatoes somewhat dry while the skin attains its specific wrinkly appearance—hence the name—and a thin layer of salt.

The dish is found in most traditional restaurants, and it is typically served as an accompaniment to hearty stews, though the potatoes can be served on their own as a simple and filling snack. Usually, the potatoes will come drizzled with mojo verde or mojo rojo—two typical Canarias sauces.
