5. Turn the meat, spoon over a little more marinade, then reduce the heat to 180°C/fan160°C/gas 4. Cook the pork for 40 minutes more.
6. Remove the pork from the oven and leave to cool. Once cooled, cut into 2.5cm slices, then chop each slice into small pieces. Stir 3-4 tbsp of the reserved marinade through the chopped pork. Chill well to firm up the filling.
7. On a lightly floured work surface, roll out the pastry to 3mm thick, then cut into 6cm squares.
8. Preheat the oven to 200°C/fan180°C/gas 6. Place 1 heaped tsp filling in the centre of each square, then fold diagonally to form a pastry triangle. Brush the inside edges of the pastry with the beaten egg, then seal all the way round with a fork. Pierce a small hole in the top of each puff to allow steam to escape.
9. Brush all over with the beaten egg yolks, then top with sesame seeds.
10. Bake for 25-30 minutes until golden. Serve with a bowl of soy sauce and rice vinegar with a green chilli (optional) chopped into it.
