Mix the eggs and sugar: In a large bowl, whisk the eggs and sugar until the mixture is pale and creamy.
Add the cornstarch: Stir in the cornstarch (or flour) and mix well to avoid lumps.
Pour in the hot milk: Remove the vanilla bean and gradually pour the hot milk over the egg and sugar mixture, whisking constantly.
Cook the custard: Pour the mixture into a saucepan and cook over medium heat, stirring constantly, until thickened. The custard should coat the back of a spoon.
Add the butter (optional): Off the heat, stir in the butter for a creamier texture.
Baking the Flan
Pour the custard: Pour the flan mixture over the pastry in the pan. Smooth the surface with a spatula. Bake: Bake for 40 to 50 minutes, until the top is golden brown and lightly caramelized.
Cool: Let cool completely to room temperature, then refrigerate for at least 4 hours before unmolding.
Enjoy

The Perfect Balance of Flavors and Textures
True French flan relies on a subtle balance: the sweetness of milk and vanilla, the richness of eggs, and the lightness of the pastry. The lightly golden surface adds a caramelized note that contrasts with the smooth custard. Each bite offers a sensation of sweetness and nostalgia.
