Just wash, rinse and sanitize the potatoes. (No need to peel)
Wrap them individually with a foil.
Place rock salt on a baking tray and arrange the potatoes on top. (Rock salt's purpose is to prevent potatoes from burning caused by direct heat and so that they will sit evenly on the tray.)
Bake potatoes at 180C until cooked.
Cut the potato on top crosswise and press to open.
Sprinkle on top with bacon bits and chives and drizzle with little bit of sour cream.
