To prepare, just scrub, prick with a fork so it won't explode—this actually happened to me once!—and pop in a 400 degree oven for one hour. (45 minutes at 450 works, too.) Wrap in foil only if you don't want the skin to crisp up.
I like to eat a baked potato for lunch with salad. I'll serve it on the side with a little organic butter, or chop it up and toss right into the mix. With avocado and salsa it's a fiesta. Or add a little of your favorite raw milk cheese, like I did today—it gets nice and melty. Mmmm.
