My first taste of this ridiculously delicious and satisfying Alpine specialty was in the middle of a 10-mile hike at a mountainside refuge high in the French Alps. Now that I've made it at home, I can tell you that you don't have to be in the Alps to love it. I can also tell you that it's probably a good idea to walk a few miles before and/or after you enjoy it. Because this is, well, not a light dish.
