WOOD SORREL SAVORY ONION TART

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.

SORREL AND ONION TART

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.

SORREL-ONION TART

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.
