Add the pork sirloin roast ... In the meantime, make the chutney. Place pineapple, Courvoisier, apple cider vinegar, onion, cinnamon and crushed red pepper flakes in a medium sauce pan.
Cook the apples in the oven alongside the pork for the final 30 minutes until soft and golden. If using as a main dish serve with the pork, along with a relish or chutney of your choice.
