Instructions

• Set up the barbecue for baking (in-direct method) and pre-heat to approximately 200°C.
• On a floured surface, roll out two-thirds of the pastry and use it to line a 23cm tart tin, leaving a slight overhang and keeping any pastry scraps. Chill the tart for 10 minutes. Prick the base lightly with a fork, then fill with baking paper and baking beans. Place on barbecue, remove the beans and paper, and then bake for 10 minutes until golden. Remove from the barbecue.
• Place the apples into a large saucepan, with 2 tbsps water and stew for 10-12 minutes, until al dente. Toss in the berries, sugar, cinnamon and 2 tbsps flour with a pinch of salt and pile it into the pastry case.
• Roll the remaining pastry and trimmings together into a square roughly 30 x 30cm. Cut out 8 strips of pastry about 3 x 30cm. Weave the strips of pastry evenly over the fruit to create a lattice pattern and push them into the edge of the tart. Trim the overhang of pastry; brush the lattice heavily with the egg, then scatter generously with more sugar.
• Bake (in-direct method) on the barbecue for 1 hour until brown and bubbling. Leave the pie to cool for 30 minutes until no longer scorching. Scatter with more sugar, slice and serve.
