I've been searching for a great gratin for a few years, and I finally found it. The original recipe calls for quarter-inch-thick potato slices, but I cut mine with a European cheese slicer, which I also used to peel the potatoes, and the slices were about an eighth of an inch thick. One more thing, be sure to let gratin rest for 10 minutes after removing it from the oven.
