This is my 3 ingredient recipe. Potatoes; white or red but no bigger than an egg, no smaller than a golf ball, this is crucial. Six or so per person is a good amount. A teaspoon of oil. Canola, peanut, olive, whatever. You can also use cooking spray. Kosher/coarse salt. A pinch or so, teaspoon is fine. Regular salt is ok but coarse is best. Put a layer of aluminum foil on a roasting pan (easier cleanup). Heat your oven to 415-450F, anywhere in this range depending what else you are making (if anything). Leave the roasting pan in there to heat up as well. Potatoes in a bowl, toss with whatever oil you've chosen. Sprinkle the salt and toss to coat. Layer it on the pan. Turn over at the 20 minute mark. Check in 20 minutes if they are tender. Usually it takes an hour but it's hard to overcook. Eat.
