What to Eat in France: Authentic Gratin Dauphinois, or Real Gratin Potatoes with Cream and Garlic
Gratin dauphinois, which consists of thinly sliced potatoes cooked slowly with cream and garlic, seems a simple enough dish. Purists and traditionalists say there’s no cheese and no egg, despite the fact that Escoffier himself used them, and that’s what makes it difficult to achieve.
Michelin star chef Michel Rostang, who was born and raised in the region, doesn’t use them and claims that’s the only authentic way to make it. In fact, if you add cheese and nutmeg, it becomes a gratin savoyard. The real secret is in the choice of ingredients and the patience it takes to make it. A good gratin should melt in the mouth, yet the top should be crunchy.
The Dauphiné was an ancient province of France, located in the southeast, corresponding roughly to the départements of Isère, Drôme, and Hautes-Alpes plus a bit of the Rhône and the Italian Alps.
