Preheat oven to 190C/Gas 5.

Cut deep slits, about an inch apart cross the top of the pork - don't go all the way through!

Season with salt and freshly ground black pepper and half of the cinnamon.

Cut one of the apples in half, and into enough slices to add to each slit that you have cut into the meat. The slices need to be fairly thin.

Cut the rest of the apples into thick slices and add them to a roasting dish with the onions. Add a little olive oil and the rest of the cinnamon and toss together.

Place the pork on top and pour over the chicken stock. Add a drizzle on top of the meat.

Cook for 30-40 minutes until the pork is cooked through.
