Lay ham on cutting board. Place two wooden spoons on either side of it and cut ham in ¼ to ½ inch thick slices, cutting just to spoons but not cutting all the way through. This method is called hasselback (see note).
1 boneless quarter ham, approx. 2.5 lbs
Place ham, sliced side up, in slow cooker.
Mix together maple syrup, Dijon mustard, brown sugar and cloves in a small bowl. Pour this mixture over ham, trying to get as much sauce between the slices as you can.
¼ cup pure maple syrup, 2 tablespoons coarse ground Dijon mustard, 2 tablespoons brown sugar, ¼ teaspoon ground cloves
Cook on low for 4 hours or until heated through, basting with sauce (spoon it over the top) every hour or so.

Notes
Have a larger ham? You can cook a ham of any size, as long as it fits into your crockpot.
Storage: Cover and refrigerate ham promptly. It will keep three to four days. Ham can be frozen in a freezer-safe container for up to two months. If you prefer, dice the ham first so it thaws more quickly and can be used in recipes.
Slicing option: If you prefer, slice the ham completely (not hasselback). Put the slices into the crockpot, retaining the original shape of the ham as much as possible.
