Preheat oven to 150°C (fan assisted). Place onion and apple slices into a roasting dish. With the back of a knife bruise the lemongrass stalk and place in the dish (if using). Make sure the roasting dish size is appropriate for the size of the piece of pork. Sit the prepared pork on the apples and onions. Pour Whitlock’s Killer Sauce for Pulled Pork
around the base of the pork and add 1 cup of water. Avoid getting the pork skin wet.
