This recipe is an enigma. It’s the story of the loaves and fishes, only in reverse. Each time I make it, I double the number of potatoes and there still aren’t any leftovers. Last week, 5 potatoes. This week, 10 potatoes. … If there is one recipe that is going to get us through those 50-lb sacks anxiously waiting for me every time I go down into the cellar, it’s this one.
