Check this out! My French sweetheart showed me this trick the other day that was so drop-dead easy, so obvious, so I-can’t-believe-I-didn’t-think-of-this, and so good, I’ve been eating my way through Parm rinds every day since. All you do is shave them to about a 1/2-inch, no less than 1/4-inch, thickness, spear them with a fork and toast them like marshmallows over a gas flame. Or if you have a broiler, pop them in the broiler. Then slice them into cubes or strips and eat. Sprinkle over salads or soups like a crouton, a pure Parmesan crouton.
