Once made, it can be eaten as is, or turned into a beautifully browned and bubbly gratin. Actually, forget I said that, as this should always be baked and eaten piping hot, ideally with some homemade crostini.
The biggest (and only) challenge with this dish is handling the salt cod. It needs to be soaked in cold water for a day or two before you can work with it. However, depending on which salt cod you use, the time this takes can vary. If you’ve never used it before, follow the instructions herein, but maybe cut off a small piece once it’s soaked, cook it in a little bit of water, and test it for salt content. It should still be kind of salty, but not unpleasantly so.
As I mention in the video, the final product should get precariously close to being too salty, without going past that point. It's going to be similar to things like smoked salmon, prosciutto, or salami. This is why you should not do any salting, including when you boil the potatoes, until everything comes together.
This is a great recipe for entertaining, since you can make it ahead of time, and bake when you’re ready to serve. You can use one large shallow dish, or do a smaller size portion like I did here. Remember everything is cooked; so all you need to do is heat it through, brown the top, and serve. I really hope you give this a try soon. Enjoy!
