Place all ingredients above in your slow cooker (use 1/8 c. marmalade if you just want a hint of orange)
Turn crockpot to low for 6-8 hrs. or high for 4 hours but honestly it is 10x better on low.
If you are cooking on high cube chicken before placing in crockpot.
Before you're ready (and hr. before is good) mix some of the hot bbq sauce in crock with cornstarch into a small bowl and then empty that into your crock to simmer for a little while and thicken sauce.
