Put your precooked ham inside your slow cooker. We had a quarter ham that fit nicely, if you have a really large crockpot you may be able to cook a half ham in it.
In a small bowl mix together your cup of brown sugar and 3/4 cup of pineapple juice. Pour this on top of your ham.
Push your whole cloves into your ham (optional). Pour 1 cup of pineapple chunks or tidbits on top of your ham, drizzle your honey on top and close your lid.
If cooking a quarter ham like we did set to low for 3-4 hours until it is warmed in the center (remember it is already cooked). If cooking a half ham (assuming you can fit that) cook on low for 6-8 or until warmed to your liking. (check temp. at min. timing to see how close to 145 F it is)
Baste the ham half way thru the cooking process with the juices at the bottom. Check internal temp. of ham in center, should reach 145 before serving.
Slice and serve drizzled with pineapple sauce in slow cooker. If you want to thicken the sauce you can dump sauce (without pineapple chunks) into a small pan on your stovetop. Take some liquid out and whisk it together with 1-3 tbsp of cornstarch in a small bowl.
Dump this back into your pot and allow to bubble until it thickens to your liking, then serve this on the side to pour on top.
