Is it a potato (pan) cake? Well, yes, and no.
Peel and very finely slice 5 baking potatoes. In a cast iron frying pan, heat olive oil and add the potatoes. Sprinkle generously with salt. Stir to cook them all a bit. Let them start to cook on one side without stirring — I did this in a more griddle-shaped pan. As they brown, move it to a 400-degree oven and finish them there. I flipped it mid-cooking. It takes about 15 to 20 minutes in the oven to cook through.
Be sure to do this in a heavy metal pan or don’t bother with it. The potatoes won’t get crispy and you’ll be disppointed. My sources tell me this is much better when made with duck or goose fat, but I didn’t have any around this time.
