SWEET POTATO SOUFFLE

Steps:

• Preheat the oven to 350°F Bake the sweet potatoes for 90 minutes or until tender. Raise oven temperature to 425°F.
• Peel the sweet potatoes as soon as they are cool enough to handle; transfer to a bowl. Using an hand held electric mixer, beat the sweet potatoes with the butter until smooth. Beat in the cream, Gruyere, brown sugar, and thyme; season with salt and pepper. Beat in the eggs one at a time, beating well after each addition.
• Transfer the sweet potato puree to a buttered 8 by 10 inch baking dish and bake for 15 minutes. Reduce the oven temperature to 400 degrees and bake for 30 minutes longer or until the sweet potatoes are lightly puffed and browned. Let the sweet potato souffle rest for 10 minutes before serving.

SWEET POTATO AND GRUYèRE GRATIN

Steps:

• Heat oven to 400 degrees and generously butter a 9-by-13-inch baking pan or shallow gratin dish. Butter a piece of foil large enough to cover top of pan. Sprinkle Parmesan all over bottom of pan.
• In a medium pot, bring cream, sage, rosemary, garlic, nutmeg and a pinch of salt to a simmer. Simmer until reduced by 1/4, about 10 minutes.
• In a large, heatproof bowl, whisk eggs just enough to break them up. Slowly pour hot cream into eggs to combine, whisking while pouring, and reserve the mixture.
• Meanwhile, using a mandoline or sharp knife, slice the potatoes into 1/8-inch-thick rounds.
• Place 1 layer of potatoes in the pan, slightly overlapping as you go, using about a third of the slices. Sprinkle with 1/4 teaspoon salt and pepper to taste, then pour 1/3 of the egg mixture over potatoes. Top with 1/2 cup Gruyère. Repeat with another layer of potatoes, 1/2 teaspoon of salt, pepper and 1/3 egg mixture. Top with 1/2 cup Gruyère. Top with remaining potatoes, 1/4 teaspoon salt, pepper to taste, and remaining egg mixture (but not the remaining cheese). Press down to compact the potatoes. Cover with foil and bake until potatoes are tender, about 40 minutes, then remove foil, sprinkle top with remaining 2/3 cup Gruyère and bake until browned and bubbling, 25 to 30 minutes. Let cool slightly, then serve.

SWEET POTATO SOUFFLE III

Steps:

• In a large stockpot, cover sweet potatoes with 1 inch of water; boil for 20 minutes, or until fork tender. Drain, allow to cool and remove skins.
• Preheat oven to 350 degrees F (175 degrees C). Grease or butter one 2 quart casserole dish.
• Place potatoes in a mixing bowl and with an electric mixer, beat on low speed until potatoes begin to break up. Increase speed to medium high and blend until smooth.
• Reduce speed to low and add sugar, milk, butter, vanilla, eggs and salt. Mix well.
• Allow any potato 'fibers' to remain on the beater and remove. Pour sweet potato mixture into the casserole dish.
• Prepare the topping in a small bowl by whisking together the brown sugar, flour, butter and pecans. Sprinkle mixture over potato mixture and bake for 40 minutes.

SWEET POTATO AND GRUYèRE SOUFFLé

Steps:

• Butter a 1 1/2-quart soufflé dish and dust it with 1/4 cup of the Parmesan. In a large heavy saucepan cook the onion and the garlic with salt and pepper to taste in the butter over moderately low heat, stirring, until the onion is softened, stir in the flour, and cook the roux, stirring, for 3 minutes. Add the milk in a stream, whisking, and simmer the mixture, whisking, until it is thickened. Remove the pan from the heat, whisk in the Gruyère, whisking until the cheese is melted, and whisk in the sweet potatoes and the egg yolks, 1 at a time. In a bowl with an electric mixer beat the egg whites with a pinch of salt until they just hold stiff peaks, whisk one fourth of them into the sweet potato mixture to lighten it, and fold in the remaining whites gently but thoroughly. Pour the mixture into the prepared soufflé dish, sprinkle the remaining 1/4 cup Parmesan over it, and bake the soufflé in the middle of a preheated 375°F. oven for 45 to 50 minutes, or until it is puffed and golden. Serve the soufflé immediately.
