Ingredients

• 1 1/2 cups all purpose flour
• 3 tablespoons sugar
• 1/2 teaspoon salt
• 10 tablespoons (1 1/4 sticks) chilled unsalted butter, cut into pieces
• 1 large egg yolk
• 1 tablespoon late-harvest Riesling or other sweet white dessert wine
• 3 large ripe Anjou pears, peeled, cored, thinly sliced
• 1 tablespoon plus 1/2 cup sugar
• 1 tablespoon all purpose flour
• 1 cup plus 2 tablespoons late-harvest Riesling or other sweet white dessert wine
• 1/2 cup water
• Vanilla ice cream

Instructions

1. Blend flour, sugar, and salt in processor until combined. Add butter; using on/off turns, cut in until mixture resembles coarse meal. Add egg yolk and wine; using on/off turns, mix just until moist clumps form. Gather dough into ball; flatten into disk. Wrap in plastic and chill at least 40 minutes and up to 2 days.
2. Position rack in center of oven and preheat to 375°F. Roll out dough between 2 sheets of parchment paper to 12-inch round. Remove top sheet of parchment and transfer dough, with bottom parchment, to rimmed baking sheet. Place pear slices, 1 tablespoon sugar, and flour in large bowl; toss to combine. Spoon pear mixture into center of dough, leaving 1 1/2-inch border. Using parchment as aid, fold up outer edge of dough over edge of filling. Bake until pears are tender, about 20 minutes.
3. Meanwhile, boil 1 cup wine, 1/2 cup water, and remaining 1/2 cup sugar in medium saucepan until syrup is reduced to 1/2 cup, about 10 minutes.
4. Reduce oven temperature to 325°F. Drizzle half of syrup over filling. Continue baking tart until juices are bubbling thickly, about 20 minutes. Cool.
5. Whisk 2 tablespoons wine into remaining syrup. Cut tart into wedges. Drizzle with syrup. Serve with ice cream.
