I know what you are thinking, with a name like this, even for Julia Child, there will be 3 pages of explanation… but follow me:
Ingredients per person:
2 slices of Gluten Free bread
2 slices of ham
4 tablespoons of sour cream or crème fraîche
6 tablespoons of shaved cheese, preferably Gruyère, you can use a vegetable peeler to do this
Preheat oven to 400°.
Spread the first bread slice with one tablespoon of cream on each side all the way to the edges. Place it in an oven proof dish or on a parchment-lined baking sheet. Top with two tablespoons of cheese, then ham folded, again two tablespoons of cheese, then the other slice of bread spread on both sides with the rest of the cream. Top with remaining cheese.
Bake until cheese is brown and bubbling, 10 to 15 minutes. Use the broiler if needed.
Now for the pronunciation, it is similar to crock-meu-ssi-eu 😉
Et voila, bon appétit !
