Make the Chutney: Simmer chutney ingredients with 50ml water for 30 minutes until thick, then cool completely.
Prepare the Base: Roll out half the puff pastry into a 22cm circle, place on a baking sheet, and spread with 2 tbsp chutney. Top with Camembert and refrigerate.
Top Pastry: Roll out the remaining pastry into a circle 5cm larger than the base. Spread 2 tbsp chutney over the cheese, cover with the top pastry, and seal the edges with a fork. Chill for 30 minutes.
Score the Pastry: Make a small 5mm hole on top, then score curved lines from the center outward. Brush with beaten egg and chill for 15 minutes.
Bake: Preheat oven to 200°C/fan 180°C/gas 6. Bake for 25-30 minutes until golden and puffed.
Cool and Serve: Let cool slightly, then slice into wedges and enjoy!
