When I was on marketplace I couldn't resist to buy this small, young potato...You don't need to peel it or anything.
The best way is to wash them, maybe a little bit peel off with brush...
and than cook it for 10 minutes. After that drain the potato, salt it, sprinkle with olive oil and parsley ant put it in pan and in an oven.
After potato is baked, wrap it in aluminium foil and leave for 5 minutes.
