Wizard’s hat pasties

The sweetness of the pumpkin and onion along with the buttery flaky pastry make these pasties good enough to eat on their own anytime

1 tbsp olive oil
small onion, finely chopped
250g pumpkin flesh (buy a large wedge and peel, or use leftovers from lantern-making), cut into small cubes of about 1cm
2 tsp tomato purée
pinch grated nutmeg
75ml vegetable stock
375g pack ready-rolled puff pastry
egg, beaten
50g cheddar, grated
2 tbsp roasted pumpkin seeds (from a packet)

Heat the olive oil in a large saucepan, then add the onion and cook for 5 mins until softened and lightly golden. Stir in the pumpkin and tomato purée. Season with nutmeg and salt and pepper to taste. Pour in the stock and bring to the boil before turning down to a simmer for 8-10 mins. The pumpkin should be just tender and almost all of the liquid evaporated. Spoon into a bowl and set to one side to cool.
Heat oven to 200C/fan 180C/gas 6. Unroll the pastry and roll it out slightly thinner with a rolling pin. Cut out 8 diamond shapes approximately 10cm wide x 15cm long.
Brush each pastry diamond with beaten egg. Stir the grated cheese into the cooled pumpkin mixture, then divide between the diamonds, placing the mix on the top half of each piece of pastry. Fold the bottom of the diamond over the filling, pressing the edges together firmly to make a well-sealed triangle. Brush all over with egg glaze and scatter over a few pumpkin seeds, in star or moon shapes if you like. Chill for 30 mins, or overnight, covered with cling film, if you are making ahead. Bake for 20-25 mins until golden and puffed.
