QUINCE-APPLE PIE

Steps:

• In a saucepan, combine quinces with reserved peel, wine, vanilla pod and seeds, 1/4 cup sugar, and enough water to cover. Place cheesecloth or a round of parchment over fruit to keep it submerged; bring to a boil. Reduce heat, and simmer until quinces are tender when pierced with the tip of a paring knife, 25 to 35 minutes. Remove fruit with a slotted spoon. Continue cooking liquid until syrupy and reduced by two-thirds, about 30 minutes.
• Preheat oven to 375°F. In a medium bowl, cover raisins with reduced poaching liquid. Let cool.
• Peel and core apples, and cut into 3/4-inch-thick wedges. Transfer to a large bowl with lemon juice, and toss to coat. Add remaining 3/4 cup sugar, the flour, and cinnamon; toss to combine. Drain raisins (reserve poaching liquid), and add to apple mixture. Using a melon baller, remove core from poached quinces, cut fruit into 3/4-inch-thick wedges, and add to apple mixture.
• On a lightly floured surface, roll out dough to a 14-inch round, 1/8 inch thick, and fit into an 8-inch cast-iron skillet, leaving overhang. Fill with apple-quince mixture, dot with butter, and fold edges over fruit, overlapping as needed and leaving center open. Brush dough with water, and sprinkle with sugar.
• Bake until crust is golden brown and juices bubble over, about 1 hour, 25 minutes. If fruit in center appears dry, brush with reserved poaching liquid. (If fruit or crust browns too quickly, tent with foil.) Transfer to a wire rack and let cool completely.
