For ease of mixing, I just tossed all the ingredients in a gallon bag and shook it up to dissolve the sugar. Then I added the chicken in and let it sit in the cooler for a couple days. You really only need to marinate overnight, but this made it easier since we were going camping.
To cook the chicken, I preheated the grill to 350 degrees, put the chicken wing sections on skewers, and cooked until they had a nice grill char on each side. I reduced the remaining marinade down and basted the chicken with it each time I turned them over (huli huli remember). I flipped them about 10 times during the course of cooking them.Happy grilling!
Notes
If you are using whole garlic and ginger you can just toss this mix in a high-power blender and blend it up to make it smooth rather than chopping up the garlic and ginger.
Putting the ginger in the freezer makes it really easy to grate and use in a marinade because it breaks down some of the rigid cellular structure and allows it to release more flavor.
