Pommes Anna (or Potato Anna) is a classic French dish of buttery sliced potatoes stacked into a cake-like form that is baked until tender on the inside and crisp on the edges. The signature presentation of a Pommes Anna is flipped over onto a serving dish where the golden brown bottom becomes the top. You must have a really good non-stick pan or a really well-seasoned cast iron pan to pull it off. Do practice this dish before serving it to guests at a dinner party. Once you can comfortably pull this off, it is a rather satisfying culinary triumph!
