A&M: 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.
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
TIPS AND TECHNIQUES
Mrsp: “This can be finished 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.”
If you can’t find sweet potatoes, use yams.

WHAT THE COMMUNITY SAID
Aliwaks: “I’m filing this away for the Seder—it’s like tsimmes, but better.”
thirschfeld: “I often add prunes to a potato galette à la The French Laundry and this held its own and then some in my book. I soaked the prunes in Cognac because I didn’t have any port. This will go into the winter rotation.”
