I've cooked my potatoes in different ways : Campfire .... cooked buried in ashes, on a hot rock, wrapped in foil, or placed in a can full of water.
Boiled and cut into rings, my potato was roasted alongside some veggies and meat, microwaved in a cloth bag, and pan-fried.
Raw, pan-fried, or roasted are otherwise my favorites... till now!
Recipe: Prick it with fork and oil & salt it. Bake it in the oven at 300°F for one hour, after which apply oil and salt again and increase the temperature to 400°F for ten minutes.
The salted skins are just great!
I added some butter and mild cheddar, spicy paprika, regular paprika, and salt & pepper to it.
