Reverse sear
Salt 24 hours ahead, uncovered in the fridge. Oven 250°F until internal 115°F — 45 to 60 minutes for a 42 oz. Rest 10 minutes. Sear in a screaming-hot cast iron with butter, thyme and garlic, 90 seconds per side. Rest 10 minutes. Slice off the bone, cut across the grain in thumb-thick slabs.
