# How to Make It:
01 - In a food processor, pulse flour, powdered sugar, and salt. Add cold diced butter and pulse until the mixture resembles coarse crumbs. Add egg yolk and 2 tablespoons ice water, pulsing just until the dough forms. Add more water if needed. Shape dough into a disk, wrap in plastic, and refrigerate for 30 minutes.
02 - Preheat oven to 375°F. Roll out chilled dough on a lightly floured surface and fit into a 9-inch tart pan, trimming excess dough. Prick the base with a fork. Line with parchment paper and fill with baking weights. Blind bake for 15 minutes, then remove weights and parchment. Bake for 8 additional minutes until lightly golden. Remove from oven and cool completely.
03 - In a large mixing bowl, toss sliced apples with granulated sugar, brown sugar, cinnamon, nutmeg, allspice, and lemon juice. In a skillet, melt butter over medium heat. Add the apple mixture and cook for 5 to 7 minutes until apples are just tender but retain their shape. Remove from heat and allow to cool slightly.
04 - In a medium saucepan, combine granulated sugar and water. Cook over medium heat without stirring until the mixture reaches a deep amber color, approximately 6 to 8 minutes. Remove from heat and carefully whisk in heavy cream, which will cause the mixture to bubble. Add butter and sea salt, whisking until smooth. Allow caramel to cool slightly before using.
05 - Arrange the cooled spiced apples evenly in the cooled tart crust. Drizzle approximately half of the salted caramel sauce over the apples.
06 - Bake the assembled tart at 350°F for 20 minutes, until the apple filling is bubbling and the crust is golden brown. Transfer to a wire rack and cool to room temperature.
07 - Drizzle the remaining salted caramel sauce over the cooled tart and sprinkle with flaky sea salt to taste. Serve warm or at room temperature, optionally accompanied by vanilla ice cream.
