SWEET POTATOES ANNA WITH PRUNES

Sweet Potatoes Anna With Prunes image

This layered sweet potato gratin comes out of the oven caramelized on the edges and glistening with butter. The potatoes in the center are soft, their layers embedded with prunes; the ones around the edges are so crisp and sweet from the port, they taste candied. Slice the potatoes thinly - use a mandoline if you have one - and check the potatoes after 35 minutes in the oven. By 40 minutes, ours were perfect.

Ingredients

1 cup (2 sticks) unsalted butter
1 cup port
10 pitted prunes
5 to 6 small sweet potatoes, peeled and very thinly sliced
Salt and freshly ground black pepper

Steps:

Clarify the butter: In a small saucepan set over low heat, melt the butter. Skim off any foam, then pour the clear liquid into a bowl, leaving behind the solids.
Heat the port to a simmer in a small saucepan over medium heat. Add the prunes, turn off the heat and let them soak until plumped, about 20 minutes. Drain and chop the prunes coarsely.
Heat oven to 450 degrees.
Brush a layer of clarified butter onto your favorite 8- or 9-inch round baking dish or ovenproof frying pan.
Arrange a layer of potatoes, overlapping in circles, in the dish. Brush with the clarified butter and season with salt and pepper. Arrange another layer of potatoes and sprinkle with about half the prune pieces. Season with salt and pepper. Brush with clarified butter. Repeat with one more layer of potatoes and prunes, then end with a layer of potatoes. Remember to brush 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 by pressing down on them with your palms. If there's a little butter left at the end, it's no big deal.
Bake until crisp and tender, 35 to 45 minutes.
Remove from the oven and let cool in the pan for a few minutes. Then flip the cake onto a serving plate and cut into wedges. If desired, finish with a dusting of sugar and a couple of minutes of broiling, for a brûlée top. It can also be made using apples and prunes, or just apples.
