Preheat your oven to 375°F (190°C). Prepare a deep dish 8-inch or 9-inch pie pan with a pie crust and refrigerate it. (Tip: Make sure your crust is nice and cold to achieve that flakey texture!)
In a large bowl, lightly beat the egg yolks and set them aside.
In a medium saucepan over medium heat, combine heavy cream, brown sugar, cornstarch, and salt. Stir continuously until the mixture thickens and comes to a rolling boil. (Tip: Keep stirring to prevent the bottom from scorching.)
Once the mixture boils, remove it from the heat.
Temper the eggs by gradually adding some of the hot cream mixture to the eggs while whisking, then add the rest of the cream mixture. Stir until smooth. (Tip: This step is crucial to avoid scrambling the eggs!)
Add honey and vanilla extract to the custard, stirring until well combined.
Pour the custard mixture into the chilled pie crust.
Bake the pie for 40-45 minutes until it bubbles up and browns slightly on top. (Tip: Keep an eye on it towards the end to avoid over-baking.)
Remove the pie from the oven; it will still be jiggly. Let it cool on the counter until it reaches room temperature and firms up. (Tip: Patience is key, as it will set more in the fridge!)
Refrigerate the pie until cold and fully set.
Just before serving, sprinkle flakey sea salt on top of the pie for that extra burst of flavor. (Tip: For an extra touch, you can drizzle a bit of honey on top before serving.)
