Step 1: Prepare the Crust

1. Make the Dough: In a mixing bowl, combine the flour, cold cubed butter, powdered sugar, and salt. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.
2. Add Egg and Water: Add the egg yolk and 2 tablespoons of cold water. Mix until the dough comes together. If needed, add an additional tablespoon of water.
3. Chill the Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.

Step 2: Prepare the Filling

1. Mix Filling Ingredients: In a large bowl, combine the ricotta cheese, honey, eggs, vanilla extract, lemon zest, cinnamon (if using), and a pinch of salt. Mix until smooth and well combined.

Step 3: Assemble the Pie

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Roll Out the Dough: On a floured surface, roll out the chilled dough to fit a 9-inch pie pan. Place the dough in the pan and trim any excess.
3. Add Filling: Pour the cheese and honey filling into the prepared crust, spreading it evenly.

Step 4: Bake the Pie

1. Bake: Bake in the preheated oven for 30–35 minutes, or until the filling is set and the top is lightly golden.
2. Cool: Remove from the oven and allow to cool for a few minutes before slicing.

Step 5: Serve

1. Drizzle with Honey: Before serving, drizzle additional honey over the top for extra sweetness.
2. Enjoy: Serve warm or at room temperature.
