Follow these simple steps to create your Honey-Glazed Nectarine Tart:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Crust: In a large bowl, combine flour and sugar. Add chilled butter and mix until the mixture resembles coarse crumbs.
3. Add Egg Yolk: Stir in the egg yolk and add cold water, one tablespoon at a time, until the dough comes together.
4. Chill the Dough: Shape the dough into a ball, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
5. Roll Out the Dough: On a floured surface, roll out the chilled dough to fit a 9-inch tart pan. Press the dough into the pan and trim any excess.
6. Blind Bake: Line the crust with parchment paper and fill with pie weights. Bake for 15 minutes, then remove the weights and parchment. Bake for an additional 10 minutes until golden.
7. Prepare Nectarines: While the crust is baking, combine honey, lemon juice, and cinnamon in a bowl. Add sliced nectarines and toss to coat.
8. Fill the Tart: Arrange the nectarines evenly over the baked crust, pouring any remaining honey mixture on top.
9. Bake Again: Return the tart to the oven and bake for another 15-20 minutes, until nectarines are tender.
10. Cool: Allow the tart to cool for at least 20 minutes before serving.
11. Garnish: Optionally, garnish with fresh mint leaves for an added touch of elegance.
