1 Place all the ingredients in a food processor and process till coarsely chopped.

2 Make several incisions in the meat and rub the marinade all over the meat and into the incisions as well. Cover with cling wrap and refrigerate overnight or up to two days.

3 Remove the meat from the fridge and leave at room temperature. Place in a casserole dish, season with salt and pepper.

4 Preheat the oven to 284°F.

5 Heat some oil and fry the onions and or shallots till soft. Add the wine, tea and sugar and bring to the boil.

6 Pour over the meat, cover and cook for about 4 hours or until soft. Remove the lid, turn up the temperature to 356°F and roast till nicely browned.

7 Place the piece of meat onto a serving platter and rest in the warming drawer for at least 10 minutes before carving.

8 Reduce the pan juices on a stove plate, adding more sugar to taste if needed. Thicken the gravy with some corn flour mixed with a little water to make a paste.

9 Serve the gravy with the meat.
