  • 1 layer frozen puff pastry, thawed
  • ½ cup (100g) granulated sugar
  • 1 teaspoon cornstarch
  • 1 cup fresh blueberries
  • 1 tablespoon lemon juice, fresh squeezed
  • 1 small egg, for brushing on pastry
  • raw sugar (or turbinado)
  • shaved white chocolate, for garnish


  • Heat oven to 375°F.
  • Unwrap one layer of puff pastry and place on a piece of parchment paper that is on a baking sheet. Trim off corners (if you want).
  • In a bowl, add sugar and cornstarch and sift together with a fork or whisk. Add in the blueberries and lemon juice and stir to coat.
  • Pour blueberry mixture into the center of the puff pastry. Start folding the edges up and over the edge of the fruit. Do this around entire puff pastry.
  • Crack an egg and beat it with a fork. Brush the puff pastry with the egg,  covering it all. 
  • Sprinkle with the raw sugar.
  • Bake for 15-25 minutes or until the pastry is a golden brown, not burnt.
  • When done, remove from oven. and let the pastry sit for at least 10 minutes, allowing the sweet fruit juices to thicken slightly. 
  • Shave white chocolate over the top and serve. (If you want the white chocolate to be melted, add this right out of the oven.)
