Now it's time to light up the kitchen torch!
Place the flame about an inch away from the ham. Keep the torch moving continually. The flame should not stay in the same spot for any period of time. Move in small circles until the area you're working on has transformed from little grains of sugar into bubbly bits of lava. Once it's bubbly, move on to the next area. Within a minute or two, the liquid will harden into a shiny crackly shell. Continue until the entire ham has a beautiful hardened sugar coating.
