Wood Sorrel Savory Onion Tart Recipes

Steps:

• In a heavy, deep saucepan, melt butter over medium-low heat. Add onions. Cook, stirring frequently, until onions are soft and translucent, about 15 minutes.
• Remove and discard the tough center ribs from the sorrel leaves. Bring a large stockpot of water to a boil, and add 2 teaspoons salt. Add sorrel, and cook just until the leaves wilt, 1 to 2 minutes. Drain sorrel in a colander, let cool, and squeeze out any excess liquid.
• Add sorrel, the remaining teaspoon salt, and the pepper to the onions; cook over low heat until mixture breaks down and is almost soupy, about 20 minutes. Remove from heat, and let cool.
• Preheat oven to 400 degrees. Line two baking sheets with parchment. On a lightly floured surface, roll one sheet of puff pastry into a 7-by-11-inch rectangle, about 1/8 inch thick. Transfer the dough to one of the parchment-lined baking sheets, and chill in refrigerator 30 minutes. Repeat process with the second sheet of puff pastry. Remove both sheets of puff pastry from the refrigerator. Using a sharp knife, score a 1/2-inch border around perimeter of each sheet, creating a picture-frame look. Using a fork, prick the entire surface within the scored edges on each sheet. Make an egg glaze: In a small bowl, combine 1 egg yolk and 2 tablespoons heavy cream; carefully brush egg glaze onto the borders.
• Transfer both sheets of dough to oven, and bake until pastry has puffed up and is golden brown, about 15 minutes. Remove pastry from oven, and transfer to a wire rack to cool.
• Add the remaining egg yolk and remaining 2 tablespoons cream to the sorrel mixture, and stir to combine. Divide the filling in two, and spread one half over each puff pastry. Return the tarts to the oven, and bake until the filling is hot throughout, about 20 minutes. Remove the tarts from the oven, and transfer to a wire rack to cool, about 10 minutes. Cut tarts into 2-inch squares, and serve warm.

Steps:

• Prepare the tart dough, partially prebake it, and set it aside.
• Melt 3 tablespoons of the butter in a wide pan, add the onion and the salt. Cover the pan, and stew slowly until the onion is completely soft, about 10 minutes. Check it occasionally and give it a stir.
• While the onion is cooking, cut off the stems of the sorrel leaves and roughly slice the leaves. Melt the remaining tablespoon of butter in a pan, and add the sorrel by large handfuls. Although the amount of leaves will seem voluminous, they will quickly cook down to almost nothing. Cook over a low heat until they have wilted and turned a grayish-green color, 3 to 4 minutes.
• Whisk the eggs with the cream; then stir in the onion, sorrel, and half of the cheese. Taste for salt, and season with freshly ground black pepper.
• Preheat the oven to 375°F. Distribute the remaining cheese over the crust; then pour the filling on top. Bake in the center of the oven until the custard is set and well colored, about 35 to 40 minutes. Serve the tart while it is hot. For wine, consider serving a chardonnay or French white Burgundy.
• This tart is based on a recipe from Richard Olney's Simple French Food.

Steps:

• Blend flour and salt in the bowl of a food processor. Scatter butter over flour, top with lid and pulse 12 pulses to cut butter into flour to a coarse meal consistency.
• Dump butter-flour mixture into a medium stainless bowl. Make a well in the center and pour ice-cold water into the well.
• Using a flexible plastic dough scraper instead of your warm hands, bring the dough together by folding and pressing. Be firm and brisk and get the dough past its shaggy stage into a neat disk, trying to avoid using your hands or too much kneading. Refrigerate the dough for 30 minutes. Heat the oven to 375 degrees.
• Meanwhile, cut the onions in half and peel them. Slice the halves with the ribs (root end to sprout end direction), not against, to create julienne slices rather than half moons.
• In a wide sauté pan over medium-low heat, melt the bacon fat and slowly sweat the onions until they are caramelized. Take all the minutes you need - 25 or so - to let them soften to translucent, then to let the water they release start to evaporate, then to allow the sugars they contain to start to brown in the pan, so that you end up with soft, sweet and evenly browned onions. This is achieved by a slow caramelization. Set onions aside to cool.
• Roll tart dough out to a 1/4-inch-thick round, and drape over a round 10-inch fluted false-bottom tart pan. Lay dough into the pan, gently pressing into the bottom, and roll the pin across the pan to cut off the excess dough. Use your fingers to press the edges into the flutes, accentuating the shape of the dough edge. Dock the bottom of the dough with the tines of a fork, weight the pastry with beans or weight and blind-bake for 25 minutes.
• In a bowl, beat the egg with the cream. Stir in the caramelized onions. Season with pepper, nutmeg and salt to taste. Stir well, and make sure the onions are all evenly coated with the custard.
• Remove tart shell from oven, and slip it onto a baking sheet. Remove weights, fill with the onion-custard mixture and distribute it evenly. Return tart to oven on the sheet, and bake for 25 minutes, or until custard has set, the tops of the onions start to achieve a deeper brown and the dough is dark golden brown at the edges.
• Remove from the ring, and allow to cool just a few minutes on the rack, so that the piping hot tart shell can kind of tighten up enough to be sliced with a sharp chef's knife. (In the first few minutes straight out of the oven, the dough is kind of soft from the heat, possibly giving you the false impression that you have a soggy tart. Let it sit on the rack just to shake off this initial soft stage and to recrisp and refirm, which it will.) Cut into wedges, and serve while hot.

Steps:

• Heat oven to 190C/fan 170C/gas 5. Roll out the pastry on a lightly floured surface and use to line a deep 23cm fluted flan tin. Line with baking paper and fill with baking beans. Bake blind for 15 mins.
• Heat the butter and oil in a large frying pan, then gently fry the onions, covered, for about 30 mins until completely softened, but still pale in colour.
• Beat the eggs and cream together in a bowl, then add the cheese and some seasoning. Stir in the onions, then spoon the mixture into the flan case. Bake for 25-30 mins until lightly set and browned.

Steps:

• Preheat the oven to 350 degrees F (175 degrees C).
• Heat butter over medium-low heat in a skillet. Cook and stir shallots and onion in butter until softened and translucent, about 5 minutes. Add garlic; cook and stir 1 to 2 minutes. Season with salt.
• Increase heat to medium. Pour white wine into the skillet and cook until evaporated. Stir in flour. Add sorrel and stir constantly for 1 minute. Remove from heat and let cool.
• While sorrel mixture is cooling, whisk together eggs, heavy cream, and black pepper in a large bowl.
• Combine sorrel mixture with egg mixture, 1/2 Gruyere cheese, and 1/2 Parmesan cheese. Pour mixture into the prepared pie crust. Top with remaining 1/2 Gruyere cheese and 1/2 Parmesan cheese.
• Bake in the preheated oven until a knife inserted into the center comes out clean and tart is firm, about 1 hour.

Steps:

• Line unpricked pastry shell with a double thickness of heavy-duty foil. Bake at 450° for 8 minutes. Remove foil; bake 5 minutes longer. Cool on a wire rack. , In a small skillet, saute onions in oil until tender; cool. In a food processor, combine the eggs, feta cheese, salt, pepper, nutmeg and hot pepper sauce; cover and process until smooth. Gradually add cream and milk; process until blended., Brush the inside of crust with mustard. Sprinkle the green onions, chives and sauteed onions over crust. Carefully pour egg mixture over onions. Top with Parmesan cheese. , Bake at 375° for 30-40 minutes or until a knife inserted in the center comes out clean.
