Glazed BBQ Chicken

2 chicken thighs with skin on and bone in
1 large onion
1/3 cup apple cider vinegar
1/4 cup honey
1-2 cloves chopped garlic
1-2 tsp hot pepper flakes
1 tsp celtic sea salt

• Peel and slice the onion and place the slices on the bottom of your crockpot.
• Place the two chicken thighs on top of the onions, bone side down.
• Mix the remaining ingredients together well and pour over the chicken.
• Cook on low for about 5 hours. 
• Remove the chicken to your plates and set aside.
• Pour the rest of the stuff in the crockpot into a frying pan.
• Bring to a boil and let it cook down until very thick.  It should coat a spoon well.  
• When the glaze is well reduced, blend it until it's very smooth.  There may be a layer of fat that does not incorporate; that's ok. 
• Once blended check the glaze for consistency.  If you think it needs to be thicker, you can return it to the pan to boil for a few more minutes. 
• Stir well to get that grease incorporated just before pouring over each piece of chicken.
