Toffee Apple Turnovers

1. Preheat the oven to 200°C (180°C fan)/Gas Mark 6. Line a baking tray with baking paper.

2. In a bowl, mix the diced apples, light brown sugar and cinnamon until well combined. Unroll the puff pastry and cut into 6 equal rectangles. Spoon the apple mixture onto one half of each rectangle, leaving a small border around the edge.

3.Fold each rectangle over the filling to create a triangle and press the edges together with a fork to seal. Transfer the turnovers to the prepared baking tray and brush the tops with the remaining beaten egg. Sprinkle with demerara sugar, if using, and make a small slit in the top of each turnover to allow steam to escape.

4. Bake for 20-25 minutes, or until the pastry is puffed, crisp and golden brown. Leave to cool for a few minutes before serving warm.
