Rinse the steak clean under cold water, and pat dry with a paper towel. Apply a dry brine with the salt, at least 2 hours before the cook.
Get your grill started, prepare it for indirect heat, roughly 120-130° C / 250-265° F.
Cook the steak on the indirect side with the lid closed until the internal temperature is 46-48° C / 115-118° F. Take it off the grill grates and let it rest while you get the fire real hot for searing.
Now it’s time to sear it. Make sure the meat surface is relatively dry, you get a lot better charring that way. Pat it dry with a paper towel if needed.
Sear the steak for a few minutes per side. It’s done when the internal temp is 54-56° C / 129-133° F. Again, remove it from the grill and let it rest a while before serving. Get a really sharp knife and separate both the strip steak and tenderloin from the bone. Now slice them, and place back on the bone for a nice presentation.
