Note: 1 1/2 pounds of Yukon gold (yellow-fleshed) potatoes, peeled, halved and mashed, should yield about 3 cups of mashed potatoes. This information will be useful if you ever want to make these cakes with mashed potatoes you have leftover from another meal.
Options: Use russet or baking potatoes instead of Yukon gold potatoes. Instead of Swiss cheese, try a different tangy cheese in these cakes, such as Gouda or aged cheddar. Shape and coat the cakes in the breadcrumbs up to a day in advance; wrap and store in the fridge until ready to cook.
