Place the pork shoulder in a large stock pot.
Add the vinegar and enough water to cover. Then add the bay leaves, onion and 4 or 5 cloves to the pot.
Cover and bring to a boil. Then, turn down the heat and simmer gently for 2 hours.
Lift the pork shoulder from the stock and place in a roasting pan. Reserve the stock.
In a small bowl mix together the brown sugar, cinnamon, nutmeg and honey. It will be a sticky paste.
When the pork is cool enough to handle, use a sharp knife to remove the skin/rind.
Make diagonal cuts in the pork shoulder about a quarter-inch deep, creating diamond patterns.
Preheat the oven to 375F / 190C.
Using your hands, rub the honey glaze over the pork shoulder.
Stud with cloves by placing one in the middle of each diamond.
Next, pour cooking stock around the ham in the roasting pan until it's about half inch deep.
Bake for 30 minutes, basting occasionally. The pork shoulder will be crisp and golden.
Use a meat thermometer to check the internal temperature of the ham to make sure it has reached 160F / 71C.
Remove from the oven, tent with foil and allow to rest for 10 minutes before slicing.
