Steps:

• Preheat the oven to 325°F (163°C).
• In a large skillet, combine the onion, 2 tablespoons of the butter, and a generous pinch of salt. Cover and cook, stirring occasionally, over medium-low heat until very tender and pale gold, about 25 minutes.
• In a large saucepan, melt the remaining 2 tablespoons butter over medium-low heat. Add the flour and cook, whisking constantly, until the mixture smells nutty, about 2 minutes. Whisk in the milk and cream in a slow, steady stream. Still whisking, bring to a boil and cook for 2 minutes. Remove from the heat and let cool slightly, whisking occasionally.
• Pour a little of the cream mixture into the eggs, whisking until completely combined. Slowly whisk this mixture back into the cream mixture in the saucepan, a little at a time, until well incorporated and smooth. Stir in the caramelized onions, then season to taste with salt, pepper, and nutmeg. Spoon the mixture onto the pate brisee, spreading it evenly.
• Bake the tart until golden brown and a knife inserted in the center comes out clean, about 1 hour. Let the tart cool in the pan on a wire rack for 20 minutes, then unmold. Slice and serve warm.

CREAMY ONION TART

Steps:

• In a mixer fitted with the paddle attachment, mix the flour, salt, butter and shortening on low speed until crumbly. With the machine running, add 2 tablespoons cold water and the egg. Beat just until the dough comes together in large clumps.
• Divide the dough in half and press each half into a 1-inch-thick round disk. Wrap each tightly in plastic and refrigerate until firm, at least 1 hour or up to 3 days; let stand at room temperature for 15 minutes before rolling. Alternatively, the dough can be frozen for up to 1 month; thaw in the refrigerator overnight.
• For each crust, on a lightly floured surface with a lightly floured rolling pin, roll 1 piece of dough into a 10-inch round. Carefully transfer the dough to an 8-inch round fluted tart pan with a removable bottom, pressing the dough gently against the bottom and up the sides. If necessary, trim the edges against the rim.
• Line the dough with foil, then fill with dried beans or pie weights. Freeze overnight, or until very hard.
• To blind bake a tart shell, preheat oven to 375 degrees.
• Bake the frozen crust until the edges are set, about 20 minutes. Remove the foil and beans. Poke holes all over the bottom of the crust with a fork, then return to the oven. Bake until the bottom is set and the crust is blonde, about 8 minutes. Let cool in the pan on a rack.
• Preheat oven to 325 degrees. In a large skillet, combine the onion, 2 tablespoons of the butter and a generous pinch of salt. Cover and cook, stirring occasionally, over medium-low heat until very tender and pale gold, about 25 minutes.
• In a large saucepan, melt the remaining 2 tablespoons butter over medium-low heat. Add the flour and cook, whisking constantly, until the mixture smells nutty, about 2 minutes. Whisk in the milk and cream in a slow, steady stream. Still whisking, bring to a boil and cook for 2 minutes. Remove from the heat and let cool slightly, whisking occasionally.
• Whisk in the eggs, a little at a time, until well incorporated and smooth. Stir in the onion, then season to taste with salt, pepper and nutmeg. Transfer the mixture to the tart shell, spreading it in an even layer.
• Bake until golden brown and a knife inserted in the center comes out clean, about 1 hour. Let cool in the pan on a rack for 20 minutes. Unmold and serve warm.

VIDALIA ONION TART

Steps:

• Preheat oven to 375 degrees F (190 degrees C.)
• In a large heavy skillet, saute butter and diced Vidalia onion. Cook until lightly caramelized. Remove from heat and whisk in sour cream. Slowly whisk in evaporated milk. Whisk in dry soup mix until completely incorporated. Whisk in eggs. Mix in the shredded cheese until blended. Spoon mixture into an unbaked pastry. Place pie on a cookie sheet and place into oven.
• Bake in preheated oven 40 to 45 minutes; or until a knife inserted comes out clean. Let stand 10 to 15 minutes.

ONION TART

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.

ALSACE ONION TART

Steps:

• Make pastry:
• Blend together flour, butter, shortening, and salt in a bowl with your fingertips or a pastry blender (or pulse in a food processor) just until most of mixture resembles coarse meal with some small (roughly pea-size) butter lumps. Drizzle evenly with 4 tablespoons ice water and gently stir with a fork (or pulse in processor) until incorporated.
• Squeeze a small handful: If it doesn't hold together, add more ice water, 1/2 tablespoon at a time, stirring (or pulsing) until just incorporated, then test again. (Do not overwork mixture, or pastry will be tough.)
• Turn out mixture onto a lightly floured surface and divide into 6 equal portions. With heel of your hand, smear each portion once or twice in a forward motion. Gather dough together with pastry scraper and press into a ball, then flatten into a disk. Chill dough, wrapped in plastic wrap, until firm, at least 1 hour.
• Roll out dough on a floured surface with a floured rolling pin into a 14-inch round and fit into tart pan. Trim excess dough, leaving a 1/2-inch overhang, then fold overhang over pastry and press against side to reinforce edge. Lightly prick bottom with a fork and chill until firm, about 30 minutes.
• Put oven rack in middle position and preheat oven to 400°F.
• Line chilled shell with foil and fill with pie weights. Bake until pastry is set and pale golden along rim, 15 to 20 minutes. Carefully remove foil and weights and bake shell until golden all over, 10 to 15 minutes more. Transfer shell to a rack. (Leave oven on.)
• Prepare filling while shell bakes:
• Cook bacon in a 12-inch nonstick skillet over moderate heat, stirring occasionally, until crisp, 6 to 8 minutes. Transfer bacon with a slotted spatula to paper towels to drain and pour off bacon fat. Add butter to skillet and cook onions with 3/4 teaspoon salt and 1/2 teaspoon pepper over moderate heat, stirring, until just wilted, about 2 minutes. Cover surface of onions with a round of parchment or wax paper (or cover skillet with a tight-fitting lid) and continue to cook, lifting parchment to stir frequently, until onions are very soft and pale golden, about 20 minutes. Stir in bacon, then remove from heat and cool 10 minutes.
• Whisk together crème fraîche, eggs, nutmeg, remaining 1/2 teaspoon salt, and remaining 1/2 teaspoon pepper in a large bowl, then stir in onions.
• Fill and bake tart:
• Pour filling into tart shell, spreading onions evenly, and bake until filling is set and top is golden, 25 to 35 minutes. Serve warm or at room temperature.
