Wrinkled potatoes - Papas arrugadas
There are several ways of cooking 'papas arrugadas' (wrinkled potatoes). This is one of the easiest ways. Cover the potatoes with peel but properly washed with water and add a quarter of a kilo of salt for each kilo of potatoes.
Let them boil, covering the cauldron. You can place a cloth or handkerchief between the cover and the cauldron, for damp to stay inside. Let the potatoes boil for half an hour. Then drain them properly. Once they are drained, let them dry or, if you want them to dry faster, make them jump at the bottom of the cauldron, keeping it on the fire.
