My great granddad used to make chicken similar to this using a basting
mixture. This is his recipe with some modifications by me to get more
browning out of it. He poured it over with a whiskey bottle and a speed
pour, I use a mug and a brush to be more efficient with the liquid. He
did it with chicken quarters, but I prefer using a spatch-cocked chicken.
He also used a different vinegar than I do.
