Baking potatoes aren’t, as some people believe, a type – the name refers to the size. Floury potatoes give the fluffiest insides when baked, but all varieties work for this comforting, low-effort meal.
Heat the oven to 190°C/Gas 5.
Put the potatoes in a baking dish and prick them a few times with a sharp knife. Rub the skins all over with a little olive oil and sprinkle with sea salt. Bake for
