Pre- heat the oven to 200c/Gas6.

Be sure to get nice big potaoes and leave them in their skins.

Wash the potaoes and then dry them.

Now rub the skins with olive oil and sprinkle with a little crushed sea salt.

Prick the skin of the potaotes here and there with a fork a few times.

Bake on the bars of a pre-heated oven for at least an hour or even 1 hour and 30 minutes.

The time will of course depend on the size of your potatoes and the variety.

The potato is done when you can easily insert a knife into it and it. And the skin should be nice and crisp. There is nothing worse than a baked potato that's not cooked through so make sure it is.

Cut a big cross on each potato and add a big dollop of butter and some salt. You don't have to add salt but it just won't taste the same.
