Add all the ingredients (except the garnishes) together in a bowl or plastic bag and combine well. Cover the bowl or seal the bag and refigerate for as long as you can. 24 hours is KING, but 2-3 hours will do the trick if you're desperate.
Preheat oven to 400ºF/200ºCTip the chicken onto a sheet pan then bake/roast in the oven for 40-50 minutes until the chicken is nice and browned.
Sprinkle over with the sesame seeds, spring onion and fresh coriander. I serve mine in the centre of the table on the sheet pan.
