Bake a Potato

Whenever I used to bake potatoes, I'd either wrap them in foil or microwave them or just throw them in the oven in a pan.  The potato skin was never crunchy and crisp.  At a restaurant a number of years ago, I asked the waitress what they did to their potatoes.  She told me to wash and dry the potato, prick it a few times with a fork, slather the whole thing with margarine(NOT BUTTER!), and then liberally cover it with kosher salt.Let it rest for a couple of hours and then bake at 350F uncovered for 45 minutes to an hour, depending on the size. Try this method...it works!!
