Eastham Turnip-Potato Gratin

Eastham Turnip-Potato Gratin

The Cape Cod town of Eastham is noted for its extra-sweet turnips, though other varieties will work in this dish. While many gratins are rich with cream, chicken broth serves as the liquid here, to delicious effect. A mandoline makes quick and even vegetable slices, though a sharp knife will do just fine. If you have a double oven, preheat the broiler while the casserole finishes baking at 350°.
