Flaky, all-butter golden pastry filled with a delicately spiced sweet filling, baked until crisp and aromatic.
Toast pecan halves on a baking sheet at 180°C for 6 minutes until fragrant; chop 1 cup coarsely.
Whisk eggs, dark syrup, dark brown sugar, melted butter, bourbon, vanilla extract, and salt in a bowl until smooth and silky.
Spread the chopped pecans evenly across the bottom of the chilled pie crust; pour the bourbon egg custard over the pecans (they will naturally float to top).
Arrange the whole pecan halves in concentric circles on the surface.
Bake at 180°C for 50-55 minutes until the center is just set with a slight gentle wobble.
Cool completely to room temperature on a wire rack for at least 2 hours to slice cleanly; serve topped with dollops of whipped cream.
