Potato And Porcini Gratin Food

POTATO GRATIN WITH PORCINI AND SOY

Steps:

• Preheat the oven to 375 degrees F. Stir together the soy sauce and mushroom powder in a small bowl and set aside.
• Add the cream, garlic and thyme sprigs to a medium pot and set over medium-high heat. Bring to a simmer, cover and remove from the heat. Let stand 15 to 30 minutes.
• Remove the garlic and thyme from the cream, then whisk in the creme fraiche, nutmeg and soy-mushroom mixture until well incorporated; season with salt and pepper.
• Assemble the gratin by putting half of the potatoes in a single overlapping layer in the bottom of a 2-quart baking dish. Coat with half of the cream mixture and sprinkle on 1 cup of the Gruyere. Repeat with the remaining potato slices, cream mixture and 1 cup Gruyere. Cover with foil and transfer the dish to a baking sheet.
• Bake until the potatoes are easily pierced with a knife, about 1 hour. Remove the foil and continue to bake until the top is golden brown and bubbling, 30 minutes. Let sit 30 minutes before serving.

POTATO AND PORCINI GRATIN

Steps:

• In a bowl soak porcini in warm water 30 minutes, or until softened. Slowly strain soaking liquid through a fine sieve lined with a coffee filter or a double thickness of rinsed and squeezed cheesecloth into a small saucepan, being careful to leave last tablespoon (containing sediment) in bowl. Boil soaking liquid until reduced to about 1/2 cup.
• Preheat oven to 350°F.
• Wash porcini under cold water to remove any grit and pat dry. Chop porcini coarse. Peel potatoes and slice 1/8 inch thick. In a large (4-quart) saucepan cook porcini and garlic in butter over moderate heat, stirring, 2 minutes. Add potatoes, reduced porcini liquid, milk, cream, 4 teaspoons chives, and salt and bring liquid to boil, stirring.
• Transfer mixture to a buttered 2-quart gratin dish and bake 1 hour, or until potatoes are tender. Sprinkle gratin with remaining 2 teaspoons chives.

POTATO GRATIN

Steps:

• Preheat the oven to 400 degrees F.
• Add the cream and milk to a large saucepan over medium-low heat and bring to a gentle simmer. Add the nutmeg, a big pinch of salt and some pepper. Meanwhile, slice the potatoes on a mandoline to 1/8-inch thick. Place the potatoes in the warm cream mixture and simmer gently until the potatoes are two-thirds of the way cooked and the cream has thickened, about 15 minutes.
• Place a 9-by-12-inch flameproof gratin dish on the stove over low heat. Brush the bottom and the sides with the melted butter. Spread the garlic around the bottom of the dish. Cook just long enough to toast the garlic in the butter, 3 to 4 minutes. Add a layer of the potato mixture. Combine the Gruyere and Parmesan in a bowl, then sprinkle a third of the cheese over the potatoes. Repeat the layering 2 more times, finishing with the remaining cheese. Pick the thyme leaves and sprinkle over the top, mixing with last layer of cheese. Place the gratin dish on a rimmed baking sheet and bake until bubbly and golden, 45 to 50 minutes (see Cook's Note).

POTATO GRATIN WITH PORCINI MUSHROOMS AND MASCARPONE CHEESE

• Place porcini mushrooms in a medium bowl and cover with boiling water. Place a small bowl atop the mushrooms so that they stay submerged in the hot water. Soak for 20 minutes, then drain and coarsely chop the mushrooms.
• Place butter and oil in a medium skillet over medium heat. When the butter has melted add the mushrooms and saute just until they begin to brown, about 3 minutes. Sprinkle with salt and pepper and remove from heat. NOTE: this step can be done the day ahead. Refrigerate the browned mushrooms until ready to use.
• Whisk 1/4 cup parmesan, the mascarpone, whipping cream, garlic and nutmeg in a small bowl. Add salt and pepper to taste. NOTE: this step can be done the day ahead - simply cover the bowl and chill until ready to use.
• Preheat the oven to 325°F Butter a wide shallow 2-quart baking dish. Arrange 1/4 of the potato slices in the bottom of the dish. Sprinkle lightly with salt and pepper. Scatter 1/4 of the mushroom mixture over all. Follow with another layer of 1/4 of the potatoes, and another layer of 1/4 of the mushrooms. Spread half of the cheese mixture over all, shaking the dish if necessary to allow the layers to settle.
• Cover the cheese layer with a layer of potatoes, a layer of mushrooms, another layer of potatoes and the last of the mushrooms. Finally spread all of the remaining cheese mixture over the top. Sprinkle the 2 tablespoons of parmesan over all.
• Place the gratin dish on a rimmed baking sheet. Bake until the top is brown and the sauce is bubbling at the edges, about 1 hour and 15 minutes. Let rest 15 minutes before serving.

WILD MUSHROOM, POTATO & PANCETTA GRATIN

Steps:

• Put the garlic cloves, onion, bay leaves, thyme, double cream and milk in a pan. Bring slowly to the boil over a low heat, partially cover with a lid and cook for 20-30 mins until the onion is tender and the cream mixture slightly thickened. Turn off and leave everything to infuse for 1 hr.
• Strain the cream mixture into a jug (or bowl) and discard the herbs. Put the garlic cloves and onion in a food processor or blender and whizz until smooth - add a drop of the cream if it helps. Stir the paste back into the rest of the cream and season with 2 tsp salt.
• Put the pancetta in a cold frying pan and cook gently, over a low-medium heat so the fat melts into the pan, until the pancetta is really crispy. Lift out with a slotted spoon, add the butter and mushrooms and turn up the heat, frying the mushrooms, until golden and dry.
• Leave the skins on the potatoes and slice as thinly as possible. Grease a large baking dish with a little more butter. Layer up the potato slices, scattering over some of the cooked pancetta, the mushrooms and a little freshly grated nutmeg and pepper as you go. Finish by slowly pouring over the cream so that it settles among all the layers, then scatter over a few more thyme leaves. Cover with foil.
• Heat oven to 180C/160C fan/gas 4. Bake the gratin for 1 hr, then remove the foil and bake for 35-45 mins more until golden and crispy on top. Poke a knife in to check the potatoes are tender, then leave for 10-15 mins to settle, before serving with a salad, if you like.
