- Preheat the oven to 200°C, fan oven 180°C/400°F/gas 6.
- With a sharp knife, slit the skins of the sausages and push the meat out into a bowl. Add the apple and mix well.
- On a floured work surface, roll the pastry out into a big rectangle as thick as a pound coin and cut it lengthways into two long, even rectangles. Roll the sausage mixture into a sausage shape with your hands and lay along the centre of each rectangle.
- Brush the long edge of the pastry with water. Then fold one side of the pastry over, wrapping the filling inside. Press down with your fingers or a fork to seal the join.
- Brush with the beaten egg and sprinkle with the black pepper.
- Cut the long rolls into bite sizes and space them out on a baking tray. Bake in the oven for 25 minutes or until puffed, golden and cooked through. Serve with pickles and chutneys.
