We love all kinds of potatoes and luckily we can eat very generous servings even during the Elimination Phase. For this recipe I prefer starchy, russet potatoes, or a blend of russet potatoes and Yukon Gold. Yukon Gold are halfway between russet and waxy potatoes, and I do not recommend you use a waxy style potato, such as a red skin potato for this dish. It will not give you the richness in texture that you need.
