Sounds really good. I would have never comes up with that, but then again I'm not a creative person. Or did you use a recipe?
Was that coconut milk and peanut butter, or something else?
Something else comes to mind. I just watched the "Barbecue" documentary on Netflix. In several areas, it's common to cook meat-on-a-stick direct, not indirect. So if you had the lid on, for heat retention, did you find yourself lifting and turning the rods often?
