1) Make the Crust: In a food processor, combine the flour, ground almonds, sugar, and salt. Pulse a few times to combine. Add the cold butter cubes and pulse until the mixture resembles coarse crumbs. Add the egg yolk and pulse again. Gradually add cold water, 1 tablespoon at a time, until the dough just comes together. Form the dough into a disk, wrap in plastic, and chill for at least 30 minutes.
2) Prepare the Filling: In a large skillet, melt the butter over medium heat. Add the pear slices, honey, cinnamon, nutmeg, and ginger. Sauté for 5-7 minutes, until the pears soften and start to caramelize. Remove from heat and let cool slightly.
3) Assemble the Tart: Preheat the oven to 375°F. Roll out the chilled dough on a floured surface to fit a 9-inch tart pan. Gently press the dough into the pan and trim any excess. Sprinkle the almond flour evenly across the bottom of the tart crust.
4) Bake the Tart: Arrange the spiced pear slices in a circular pattern over the almond flour. Drizzle any leftover juices from the pan over the pears. Bake for 30-35 minutes, until the crust is golden and the pears are soft. During the last 5 minutes of baking, sprinkle the sliced almonds over the tart for added crunch.
5) Serve: Let the tart cool slightly before serving. The warm spices, honeyed pears, and almond crust pair beautifully with the earthy, fruity notes of Domaine Carneros Estate Pinot Noir.
