Method
In a medium saucepan, bring the whole milk and the scraped vanilla bean seeds and pod to a gentle simmer at 85C/185F. Remove from heat and steep for 15 minutes to infuse the flavors.
In a mixing bowl, vigorously whisk the egg yolks, granulated sugar, and cornstarch until the mixture becomes pale yellow, thick, and smooth.
Remove the vanilla pod from the steeped milk. Gradually pour half of the hot milk into the egg yolk mixture while whisking constantly to safely elevate the temperature of the eggs without scrambling them.
Pour the tempered egg mixture back into the saucepan with the remaining milk. Cook over medium heat, whisking continuously, until the mixture thickens and reaches a vigorous boil at 100C/212F. Boil for exactly 1 full minute to thoroughly cook out the raw starch flavor and stabilize the cream.
Remove the saucepan from the heat and whisk in the cubed butter until fully emulsified. Transfer the pastry cream to a clean bowl, press a sheet of plastic wrap directly onto the surface to prevent a skin from forming, and refrigerate until completely firm.
Preheat the oven to 200C/400F. On a lightly floured surface, roll the cold puff pastry to a 3mm thickness. Place it on a parchment-lined baking sheet and pierce the surface all over with a fork to prevent irregular rising.
Cover the pierced pastry with a second sheet of parchment paper and set a heavy second baking sheet directly on top. Bake in the preheated oven for 15 minutes to set the layers in a compressed state.
Remove the top baking sheet and parchment paper. Evenly sift the 30g of icing sugar over the surface of the partially baked pastry. Increase the oven temperature to 220C/425F and return the pastry to the oven for 5 to 8 minutes, watching closely, until the sugar melts into a glossy caramel.
Transfer the caramelized pastry to a wire rack to cool completely. Once cool, use a serrated knife and a gentle sawing motion to trim the edges neat, then slice into 18 uniform rectangles, measuring approximately 10cm by 4cm each.
Transfer the firm, chilled pastry cream to a piping bag fitted with a 1cm round tip. Arrange 6 pastry rectangles as the base layer. Pipe neat, uniform dollops of cream across the surface of each base. Gently place a second pastry rectangle on top of each, and repeat the piped cream layer.
Top with the final 6 pastry rectangles. Decorate the crown with remaining piped pastry cream and carefully arrange the fresh golden raspberries on top. Dust lightly with icing sugar just before presenting. Serve within one hour to ensure peak crispness.
Chef's Notes
- Weighing down the puff pastry is non-negotiable for a classic mille-feuille. This technique forces the lamination to bake outward horizontally rather than puffing vertically, creating incredibly dense, crisp, and shattering layers.
- Golden raspberries offer a slightly milder, sweeter, and more floral flavor profile than their red counterparts, which pairs perfectly with the intense vanilla notes of a well-made creme patissiere.
- Mille-feuille literally translates to a thousand leaves and is notoriously susceptible to ambient humidity and moisture from the cream. Always assemble the dessert no more than an hour before serving to maintain the crucial textural contrast.
- When tempering the eggs for the pastry cream, ensure your milk is hot but not boiling over. The goal is to slowly raise the temperature of the yolks so they do not scramble into sweet scrambled eggs.
Storage
Refrigerator: 1 day — Assembled pastry becomes soggy quickly. Store components separately for up to 3 days.
