Bake the potatoes
40 minWash and scrub the potatoes with their skins on, then dry them thoroughly. Pierce each one in three or four places with a fork, rub with olive oil, and sprinkle with half the salt. Arrange them on a parchment-lined baking sheet and bake in an oven preheated to 200°C / 390°F for 40 minutes. They are done when a skewer slides into the thickest potato without resistance.
