I wonder if its because you're using a halogen oven? Where is the heat source? In a normal oven (heat from the sides) I wouldn't expect puff pastry to burn in 15 minutes. I cooked a sausage plait at the weekend and even after 30 mins at 180C the pastry was only just light golden.The sausage was not cooked enough for me and the pastry would have burnt if I'd have cooked it longer. That was 5 minutes at 200 degC and 10 minutes at 180 degC. Halogen oven, lower rack. I think my next experiment will be to stir fry the pork mixture for a few minutes before forming the roll.
Do you have a photo of it before it was broken up?
