Ingredients:

  • 3 medium (300g) Granny Smith apples, peeled and finely diced
  • 3 tbsp (42g) unsalted butter
  • 1/4 cup (50g) brown sugar
  • 1 tsp (2g) ground cinnamon
  • 1 tbsp (15ml) lemon juice
  • 1/4 tsp (1g) salt
  • 1 sheet (250g) frozen puff pastry, thawed but chilled
  • 1 large (50g) egg, beaten
  • 1 tbsp (15g) granulated sugar

Instructions:

  1. Melt the butter in a skillet over medium heat.
  2. Add the diced apples, brown sugar, cinnamon, lemon juice, and salt to the skillet.
  3. Cook for 5–8 minutes, stirring occasionally, until the apples are tender and the liquid has reduced to a thick, velvety glaze.
  4. Remove the apple mixture from heat and let cool for 10 minutes to prevent the pastry from melting.
  5. Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
  6. Roll out the chilled puff pastry sheet slightly on a lightly floured surface to even out the thickness.
  7. Using a knife or pizza cutter, slice the pastry sheet into 8 equal squares.
  8. Lightly score a smaller square inside each piece (about 1/2 inch from the edge), being careful not to cut all the way through.
  9. Place the squares on the baking sheet and spoon a generous amount of the apple mixture into the center of each square.
  10. Brush the outer borders with the beaten egg wash and sprinkle granulated sugar over the edges.
  11. Bake for 20–25 minutes until the edges are mahogany-colored and have risen significantly.
