Unpack your ham and dry it off
Place in a tin on a rack..
Apply your coffee rub mixture all over the ham. If you have some left over just disregard it.
You want the coffee mixture to fall in the tin.
Let rest so the ham comes up to room temperature
Preheat your Z GRILLS 275f
Once you hit 275 put your ham in and heat it to 120f (approximately 5 hours)
You can speed the process along after hour 3 by adding 1/2 cup water and loosely wrapping with foil..
Once 120 is reached, turn the pit up to 450f and start mopping. Mop until you are happy with the color. Also a good eating temperature for the ham is 140f.
Once 140 is hit remove and baste with some of that sauce on the bottom of the tin.
