Papas arrugadas ([ˈpapas aruˈɣaðas] "wrinkly potatoes") is a traditional baked potato dish eaten in the Canary Islands. They are usually served with a pepper sauce, called Mojo, or as an accompaniment to meat dishes.
The dish is made from small new potatoes which are cleaned (but not peeled), then boiled in water (originally in seawater, but it is more usual that salt is added to the water in the boiling process) and then baked in their skins until they become shrivelled. Alternatively, in some recipes, after cooking in salted water most of the water is discarded and the small amount that remains is boiled away until the potatoes become dry. This leaves them with a characteristic dry salt crust on their skins.
The potatoes have to be the smallest the cook can find; if not, the potatoes will miss their supposed flavour[clarification needed] and they will not absorb all the sauce.
They are considered the "main dish" or the "star dish" of the Canary Islands cuisine.
