Bring half a pot of water to a boil, add the trotter and blanch for 5-6 minutes. Remove and drain. Combine sauce ingredients and water in a deep saucepan. Cook to a boil then add the trotter. Lightly cover and simmer over low heat for 1-1½ hours until meat is just firm yet tender.
Remove the trotter and brush with combined honey mixture. Place the trotter on a roasting rack. Grill in a preheated oven at 190°C-200°C for 15-20 minutes, or until the trotter skin is lightly golden brown and crispy.
