I was doing some research for the blog this morning when I accidentally found a picture of these potatoes on another blog.
I researched the recipe and discovered that it was originally from Martha Stewart.
I would make it in a 9" - 10" Cast Iron Skillet or even a Dutch Oven.
Since I don't have the rights to re post the picture, I would suggest that you research the recipe to see how they're made. They're standing up in the skillet and not layered. The tops of the slices become crispy........ pure genius!
Here's a note that I found at the end of the research:
Keep the slices together as you slice them so that they can be arranged easily in the skillet.
