Put the pieces into a roasting tin such that they are in a
single layer.
Season with salt and pepper.
Mix together the other ingredients in a bowl.
Pour the mixture over the belly pieces in the roasting tin,
making sure that they are all thoroughly coated.
Cover the roasting tin with tightly-fitting foil.
Cook for at least 1.5 hours, until the belly slices are
tender.
Remove the foil and place the roasting tin under a very hot
grill for three to four minutes, turning the belly slices half
way through and brushing the sauce over the slices until the
sauce is thick and the slices slightly charred.
