Slow Cooker Sesame Orange Chicken

I often find recipes on the net that sound good but I'm either not excited about the ingredients or I can't find them. The later was true of this recipe. It called for a honey bbq sauce which I could not find. This is a Chinese recipe and I just couldn't justify adding bbq sauce to it. So out it went and I went hunting in my pantry and the condiment section of my frig.
Serves 4-6

4 pound boneless skinless chicken thighs
3/4 cup flour
zest and juice of 2 large oranges
1/2 cup orange sauce(I found this in the oriental foods section at the grocery store. You can use 1/4 cup frozen orange juice concentrate instead)
1/2 cup orange marmalade or apricot jam
1/3 cup ponzu or soy sauce
3 tbsp rice vinegar
1/4 cup teriyaki sauce
1/2 tsp of chili garlic sauce(add this if you like heat)
2 tbsp cornstarch dissolved in 1/4 cup water(optional)
sliced green onions and sesame seeds for garnish

Place the flour in a large zip lock bag. Add the chicken, seal the bag and toss to coat. Remove the chicken from the bag and place it in the bottom of the slow cooker insert. Mix all the next 7 ingredients in a bowl and pour it over the chicken. Cook 3 hours on low and 3 hours on high. Serve over rice, garnish with green onions and sesame seeds.
