01 - Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - In a mixing bowl, combine the finely diced apples with granulated sugar, ground cinnamon, and lemon juice. Toss to coat evenly and set aside.
03 - In a separate mixing bowl, blend the ricotta cheese, honey, and vanilla extract until a smooth consistency is achieved.
04 - Gently roll out the thawed puff pastry sheet and cut it into 8 equal squares.
05 - Spoon a portion of the ricotta mixture into the center of each puff pastry square. Top the ricotta with a spoonful of the prepared apple mixture.
06 - Carefully gather the corners of each pastry square and pinch them together at the top, ensuring the edges are sealed to create a blossom-like appearance and contain the filling.
07 - Generously brush the exterior of each assembled pastry blossom with the beaten egg for a golden finish.
08 - Place the brushed pastry blossoms onto the prepared baking sheet. Bake for 18 to 20 minutes, or until the pastries are puffed and golden brown.
09 - Allow the pastries to cool slightly on the baking sheet. Just before serving, lightly dust with powdered sugar.
