So I decided to do a Spatchcock chicken using coconut oil instead of evoo, and coconut sugar substituted in a homemade rub.
Following directions found here - raised direct @ 400 - it turned out looking perfect, but the rub needs a bit of tweaking.
Also the skin was a bit rubbery when it cooled.
But overall for a my virgin bird it was ok.
Saw a couple suggestions around using a higher temperature or leaving uncovered in fridge - will try that next time.
