Preheat oven to 220°C. Line a baking sheet with parchment paper.

Using a 6–7.5 cm biscuit or cookie cutter, cut 6 rounds from the thawed puff pastry sheet and arrange on the prepared tray.
03 -
Combine raspberries, sugar, flour, salt, and lemon juice in a bowl; toss gently until well coated.
04 -
Spoon some raspberry mixture onto the centre of each pastry round. Sprinkle each with 1–2 tablespoons chopped dark chocolate, reserving some chocolate for finishing.
05 -
Gently fold the edges of each pastry round up and around the filling to create a rustic border.
06 -
In a small bowl, whisk together the egg and water. Brush the folded pastry edges with the egg wash using a pastry brush.
07 -
Transfer to oven and bake for 12–15 minutes, or until the pastry is golden brown and puffed. If needed, extend bake time slightly for full colour and crispness.

While tarts bake, melt reserved dark chocolate in a microwave-safe bowl at 50% power in 30-second intervals, stirring between each, until smooth.

Drizzle melted chocolate over baked tarts. Serve warm or at room temperature.
