Peel a strip from around the center of each potato, like you’re taking off its “belt”.
Place partially peeled potatoes into a pot and cover with water. Put over high heat and cover with a lid. Boil for 8 minutes until almost tender. Drain.
Back into the pot, add the butter over medium heat. Add potatoes and swirl the pan to coat in butter. Cook for about 8-10 minutes, swirling occasionally until all sides are browned.
