This dish is worth waiting for. The trick is to let the beef marinate for 24 hours before slow cooking it for 4 hours. The result is an amazingly flavourful stew and tender meat.
Place all ingredients except cornflour into a large, lidded, ovenproof casserole dish and leave to marinate in the fridge for 24 hours.
Preheat oven to 160 C / Gas 3. Remove the chilled and marinated stew from the fridge and give a little stir.
Bake in the preheated oven for 1 hour until bubbling.
Reduce the heat to 150 C / Gas 2. Bake for a further 3 hours, or until meat is very tender. Allow to cool, then chill in the fridge for at least 8 hours.
Skim off any fat, remove and discard the orange peel and bay leaves, then stir in cornflour paste.
Reheat at 190 C / Gas 5 for 45 minutes, by now the stew should be very thick and hearty.
