Heavily and generously salt the entire steak, including the bone, cover with saran wrap, and set in the fridge until about an hour before cooking. (I like to use a good flakey sea salt.)
Take the steak out and bring it up to room temperature.
Preheat your oven to 225°F and insert a meat thermometer in the middle of the steak.
Cook until the internal temperature reaches 131°F.
Heat your grill or BBQ to high, then sear the steak for a few minutes on each side.
