Pistachio and Raspberry Mille-Feuille

Introduction

The mille-feuille is a classic French pastry made with layers of flaky puff pastry, pastry cream, and fruit preserves. In this recipe, we will combine pistachio-flavored pastry cream with raspberry jam for a unique twist on the traditional dessert.

Ingredients

For the Puff Pastry:

• 1 package (thawed) frozen puff pastry, homemade or store-bought
• 1/4 cup confectioners' sugar

For the Pistachio Cream:

• 1 cup (250ml) heavy cream
• 2 tablespoons (30g) unsalted butter, softened
• 1 teaspoon vanilla extract
• 1 tablespoon pistachio paste
• 1 cup (200g) granulated sugar

For the Raspberry Jam:

• 1 cup (200g) raspberry jam
• Confectioners' sugar for dusting

Instructions

Prepare the Puff Pastry

1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Roll out the puff pastry on a lightly floured surface to a thickness of about 1/8 inch (3mm).
3. Transfer the pastry to the prepared baking sheet and bake for 20-25 minutes, or until golden brown.

Prepare the Pistachio Cream

1. In a medium saucepan, combine the heavy cream, butter, vanilla extract, pistachio paste, and granulated sugar.
2. Cook over medium heat, whisking constantly, until the mixture comes to a boil.
3. Reduce the heat to low and simmer for 5 minutes, or until the mixture has thickened slightly.

Assemble the Mille-Feuille

1. Allow the puff pastry to cool completely on a wire rack.
2. Spread a layer of pistachio cream on top of each sheet of puff pastry.
3. Top with a layer of raspberry jam and repeat the process until you have used up all of the ingredients, finishing with a layer of puff pastry.
