CARAMELIZED PEAR TART WITH CORNMEAL CRUST

Steps:

• Make dough:
• In a bowl whisk together flour, cornmeal, sugar, and salt. Cut butter into 1/2-inch cubes and add to flour mixture. With your fingertips or a pastry blender blend in butter until most of mixture resembles coarse meal with remainder in small (roughly pea-size) lumps. Drizzle 4 tablespoons ice water evenly over mixture and gently stir with a fork until incorporated. Test mixture by gently squeezing a small handful: When it has proper texture it should hold together without crumbling apart. If necessary, add enough remaining water, 1 teaspoon at a time, stirring until incorporated and testing, to give mixture proper texture. (If you overwork mixture or add too much water, pastry will be tough.)
• Turn mixture out onto a work surface and divide into 4 portions. With heel of hand smear each portion once in a forward motion to help distribute fat. Gather dough together and form it, rotating it on work surface, into a disk. Chill dough, wrapped in plastic wrap, until firm, at least 1 hour, and up to 1 day.
• Preheat oven to 400°F.
• Make caramelized pears:
• Peel pears and halve lengthwise. Cut each half into 3 wedges and core. In a 10-inch cast-iron skillet melt butter over moderate heat and stir in sugar. Cook mixture, stirring frequently, until sugar is dissolved and mixture is golden, about 6 minutes. Remove skillet from heat and let mixture stand until it begins to firm up, about 3 minutes. Arrange pears, rounded sides down, as close together as possible in 2 concentric circles in skillet.
• On a lightly floured surface roll out dough into a 15-inch round (about 1/8 inch thick) and cut out an 11-inch round. Drape round over pears, tucking edge around pears, and with a fork prick dough in several places. Bake tart in middle of oven until pastry is golden and cooked through, 40 to 45 minutes. Cool tart in skillet on a rack 15 minutes.
• Invert a rimmed serving plate slightly larger than skillet over skillet and, wearing oven mitts and keeping plate firmly pressed against skillet, invert tart onto plate. Arrange any loose pears on tart and spoon sauce from plate onto tart. Serve tart warm or at room temperature.
