DOC.Lake house on Lake Huron here... near Pt Huron....
Romney has a place down the beach, his family's home for 60+ years
For chicken wings, etc I have firebricks, actually for nay slow cooked meats
You need a second grill...
use the bricks (3) on your main level grill
Stack the second (smaller) grill on the bricks to raise off the higher heat.
Our RD friend Lindsey Kaufman put me on to Adam Perry Lang - look him up.
I use the 'brick lift' in Cabrera for wings, ribs - you name it.
Wings go up after searing and stay there, untouched for 45 min or so
Then slather on your sauce.....
The RD built grills have several notches for lifting and lowering the meat on the grill
I'm going to invest in one..... they make them custom.
Like an outdoor fire with cooking ability.
sort of like this.....
