01 -
Prepare a pie crust and bake it fully blind following your go-to recipe or instructions.
02 -
Use a sharp knife to finely chop chocolate. Put the chopped pieces in a large bowl under a fine-mesh strainer.
03 -
Heat butter in a light-colored saucepan so you can spot changes. Keep gently stirring as it melts, bubbles, and starts smelling nutty when the milk solids turn browned at the bottom.
04 -
While whisking, pour the milk into the browned butter to help cool it. Mix in sugar, egg yolks, and salt. Over medium-low heat, cook and whisk until the custard gets a bit thicker and hits 160°F (70°C).
05 -
Strain the warm custard liquid through the mesh sieve onto the chopped chocolate. Let it sit undisturbed for about 20 seconds, then stir to combine it all. Drop in the vanilla and mix until smooth with no chocolate bits left.
06 -
If the mixture looks like it’s breaking apart, quickly stir in the sour cream, then the extra milk, until the texture becomes glossy and combined, like ganache. Bits of browned butter will still be noticeable—pour this filling into your crust.
07 -
Refrigerate the pie for 4+ hours until it’s completely firm.
08 -
Measure the cream and other topping ingredients into a food processor. Process on high for 1-3 minutes till thick and airy, then spread the whip over the chilled pie.
