Combine honey and English mustard together and brush half as an even coat all over the gammon and reserve the other half for later.
Combine all seasonings together a sprinkle an even layer all over the gammon.
Set Smoker to 110C and once up to temperature set the smoke on. I use apple wood.
Add the gammon to the smoker with a tray on the rack below to catch any drippings and juices and smoke for 3-4 hours.
After this time has passed you can turn the smoke off, use the rest of the honey and mustard mixture as a final glaze and continue to cook for another 1-2 hours until an internal temperature of 75C is reached.
