Add water and salt to a large pot, stir to dissolve the salt as much as possible. Add the potatoes. If more water is needed to cover the potatoes, add an extra 2 tablespoons of salt per cup of water added.
Bring to a boil and cook until the potatoes are just fork tender, about 15 minutes.
Drain the potatoes and let them dry to form the salt crust on the outside.
Drizzle with melted butter when serving.
