A great big thank you to Chef Mark Brown from the Facebook community Fun in Being a Foodie!
Mix the salt, pepper, cinnamon, nutmeg, and brown sugar well and rub the chicken with it. In a large heavy skillet over medium high heat melt the butter and brown the chicken for 4 minutes on each side. Mix the remaining ingredients well in a well sprayed crock pot, add the chicken and turn a few times to coat well. Cover and cook on high for 4 hours or on low for 6.
Depending on how much moisture the chicken has you may need to add a slurry of cornstarch and water halfway through cooking. 2 tsp of cornstarch and cold water mixed and stirred in. I did.
