Ingredients

Scale
  • 1 package (about 14 oz / 400 g) frozen puff pastry sheets, thawed
  • 1 egg, beaten (for egg wash)
  • 1 tablespoon granulated sugar (optional, for sprinkling)
  • 3 large eggs, room temperature
  • 1 cup (200 g) granulated sugar
  • 1/2 cup (120 ml) fresh lemon juice (about 34 lemons)
  • Zest of 2 lemons
  • 6 tablespoons (85 g) unsalted butter, cut into pieces
  • 1 cup (150 g) fresh or frozen wild blueberries (if frozen, thaw and drain excess liquid)
  • 1 tablespoon honey or maple syrup (optional, to sweeten berries)
  • 1 teaspoon lemon juice (to brighten flavor)
  • Powdered sugar, for dusting
  • Fresh mint leaves (optional, for garnish)

Instructions

  1. Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
  2. Unfold thawed puff pastry sheets on a lightly floured surface and gently roll out to smooth creases, about 10×12 inches (25×30 cm) per sheet.
  3. Prick pastry all over with a fork to prevent excessive puffing.
  4. Brush top lightly with beaten egg and sprinkle with sugar if desired.
  5. Bake for 15-18 minutes until golden and crisp. Remove and cool completely on a rack.
  6. In a medium saucepan, whisk together eggs, sugar, lemon juice, and zest.
  7. Cook over low heat, stirring constantly, until mixture thickens and coats the back of a spoon (8-10 minutes).
  8. Remove from heat and stir in butter until melted and incorporated.
  9. Strain lemon curd through a fine mesh sieve into a bowl. Cover with plastic wrap touching the surface and chill for at least 1 hour.
  10. In a small bowl, gently toss blueberries with honey and lemon juice. Let sit for 10-15 minutes.
  11. Cut cooled puff pastry sheets into rectangles about 3×4 inches (7.5×10 cm).
  12. On a serving plate, place one pastry rectangle, spread a generous spoonful of lemon curd evenly over it, then scatter some wild blueberries on top.
  13. Repeat layering to build 2-3 tiers, finishing with a pastry sheet on top.
  14. Dust the top layer lightly with powdered sugar and add fresh mint leaves for garnish.
  15. Serve immediately to keep puff pastry crisp, or chill up to 2 hours before serving.

Notes

Bake puff pastry sheets separately to keep layers crisp. Use a fine mesh sieve to strain lemon curd for smoothness. Assemble dessert just before serving to maintain puff pastry crunch. If lemon curd is too tart, add a pinch more sugar during cooking. Avoid soaking blueberries too long to prevent sogginess. Leftovers can be refrigerated up to 2 days; re-crisp pastry in a 350°F oven for 3-5 minutes before reassembling.
