Preheat oven to 180°C/350°F
Heat the oil in a large lidded flameproof casserole and brown the meat.
Add the pommeau and stock so that the meat is semi-covered and bring to a simmer then cover and put in the oven for 1 hr.
Add the peeled and cored apple for the last 30 mins of cooking so that they cook through but retain their shape.
Remove from oven and reduce sauce if needed and season to taste.
Serve with mashed potato and greens if you like.
