Step 1: Prepare the Crust

• In a large bowl, combine the flour, sugar, and salt.
• Add the cold butter cubes and use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.
• Add the egg yolk and ice water, one tablespoon at a time, until the dough starts to come together.
• Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes.

Step 2: Prepare the Filling

• In a large bowl, toss the sliced apples with honey, sugar, lemon juice, cinnamon, nutmeg, and flour.
• Make sure all the apple slices are evenly coated. Set aside.

Step 3: Assemble the Tart

• Preheat the oven to 375°F (190°C). On a lightly floured surface, roll out the chilled dough to fit a 9-inch tart pan.
• Press the dough into the pan and trim the edges.
• Arrange the apple slices in a circular pattern over the crust, overlapping slightly.
• Pour any remaining honey mixture over the apples.

Step 4: Bake the Tart

• Bake in the preheated oven for 40-45 minutes, or until the apples are tender and the crust is golden brown.
• While the tart is baking, prepare the glaze by heating the apricot jam and water in a small saucepan until melted and smooth.
• Brush the glaze over the warm tart right after it comes out of the oven.
