Crusty Salt Baked Potatoes

I got this recipe from some restaurant but I don't remember where.

Ingredients:
1 potato per person (I usually use Idaho baked potatoes)
Sea or Kosher Salt
2 tin foil squares large enough to wrap the potatoes

Directions:
Wash the potatoes and cut out the eyes out on the potatoes
Lay potatoes on tin foil squares
Shake Sea or Kosher Salt over potato
Wrap potato in Tin Foil
Put directly on middle rack in oven

Bake at: 400 degrees
Time: 60 Minutes
