Lower the oven temperature to 170°C (340°F).

In a large bowl, whisk together the brown sugar, granulated sugar and eggs until thick and smooth and lighter in colour. 150 g brown sugar, 100 g granulated sugar, 2 large eggs
Add the melted butter, cream, vanilla, salt, and flour and until the mixture is smooth.60 g butter, 3 tablespoons heavy cream, 1 tablespoon all-purpose flour, 1 teaspoon vanilla paste, ½ teaspoon salt
Scatter the chopped pecans evenly over the base of the crust. Pour the filling over the top, then arrange the pecan halves neatly over the surface.
Bake the pie for 40–50 minutes, until the edges are set and the centre still has a slight wobble when you gently shake the pan. Every oven is different, so check your pie near the end of the baking time.
If your pie crust edges are browning too fast, cover them loosely with foil halfway through baking.
Let the pie cool completely before slicing and serving.
