With Whole Foods having more of these excellent steaks, I decided to document my procedure. This steak was about 1.5" thick and about 1.3 lb.
Cast iron on high for 20 minutes.
Wash the pan with some peanut oil, drain, throw in your steak that has been heavily salted and peppered. Note that this side wasn't, thinking too much about documenting vs. cooking.
Steak goes in the oven at 400F for 4 minutes. Pull out steak and put on a plate. Throw some finely diced shallots and a tiny amount of garlic and good bit of butter in the pan, put on low heat. Tonight I added some fresh dry rosemary and thyme.
Steak rested for 10 minutes, sliced, buttered, rare, perfect. You can see the veins of fat throughout. So tender.
