Found this 2.5 lb prime tomahawk ribeye at Costco for $30. The miracle 3 hour salt brine from Butcher Betties, our coffee garlic rub, an hour and a a half on the charcoal to reverse sear it to medium rare and then to the gas grill and cast iron at 800 degrees for two minutes a side.
Dinner for two with leftovers for another two meals. Best steak I've ever cooked. Huzzah.
