This recipe is popular in the canton (region) of Vaud, which is located in Romandy, the French-speaking southwestern part of Switzerland. They are rustic and delicious! I modified the recipe because the original called for lard and I didn't see any reason to waste good bacon fat! Also, they want you to boil your potatoes whole, cool, then peel and dice them but I couldn't really see why you need to take the extra steps. Enjoy!
