Recipe Instructions:
5-6 sweet potatoes, sliced very thinly using a mandoline
1/2 pound butter
1 cup port
10 pitted prunes
Melt 1/2 pound butter and clarify. (Skim off the foam & milk solids until all that remains is clear butterfat.)
Heat a cup of port and soak ten pitted prunes until slightly plumped, about 20 minutes. Drain and chop the prunes coarsely.
Preheat oven to 450.
Brush clarified butter onto your favorite eight- or nine-inch round baking dish or oven-proof frying pan.
Put a layer of potatoes, overlapping in circles, in the dish. Brush with clarified butter, and salt and pepper. Put another layer of potatoes and about half the prune pieces. Salt and pepper. Brush with clarified butter. Repeat two more layers, embedding the rest of the prunes at the end and brushing each layer with clarified butter and salt and pepper. You can do four layers of potatoes or six, it's up to you. Pack the potatoes tightly. If there's a little butter left at the end, it's no big deal.
Bake at 450 for 45-60 minutes until crisp and tender.
Remove from oven when crisp and tender. After a few minutes, flip onto a serving plate.
