As far as I'm concerned, a simple gratin is the most delicious way to cook fresh scallops. The only real way to screw this recipe up would be to use the wrong scallops. And by wrong, I mean any scallops that have been soaked in a preservative brine. These are easy to identify, as they're usually sitting in a pool of milky liquid. What you want are usually sold as wild 'day-boat,' 'diver,' or 'dry-pack' scallops. They are really expensive, and worth every penny. Serve with French bread for dipping.
