Ingredients
Scale
- 1 to 2 tablespoons fine, dry bread crumbs
- 2 very large sweet potatoes, peeled and cut into 1-inch cubes
- 2 teaspoons olive oil
- Kosher salt, to taste
- 1/2 cup whole milk
- 4 tablespoons butter, softened
- 1/4 cup brandy
- 1/8 teaspoon cayenne
- 1/4 teaspoon ground nutmeg
- 1/2 teaspoon salt, or more to taste
- 1 generous teaspoon lemon zest
- 4 eggs, separated
Instructions
- Preheat oven to 400 degrees.
- Butter a 1-quart soufflé dish and coat inside with fine bread crumbs, tilting and turning dish to coat sides completely.
- Place sweet potato cubes in a large roasting pan; toss with olive oil and sprinkle with kosher salt to taste. Roast, stirring occasionally, about 30 to 35 minutes or until very soft. Cool slightly, then transfer to a food processor. Pureé until smooth to yield 2 cups. (Freeze any extra pureé for other use.)
- In a small saucepan (or glass bowl in the microwave), heat the milk until hot but not boiling.
- In the bowl of an electric mixer, beat together the hot milk, mashed sweet potato, butter and brandy, mixing until smooth. With machine running, add the cayenne, nutmeg, salt, lemon zest and 4 egg yolks.
- In a clean bowl, beat the 4 egg whites until stiff peaks form (do not overbeat). Fold egg whites into sweet potato mixture; pour into prepared soufflé dish. Bake for 25 to 30 minutes or until well puffed and browned on top. Serve immediately.
