Heat cast iron skillet on grill or stovetop. Salt and pepper steak generously. In hot skillet, add olive oil, which will start to smoke, then add steak and sear until browned well. Turn steak on fat side, searing the fat edge for approx. 1 min. Flip steak to uncooked side, searing 2 min. Add garlic, herbs and butter. Baste steak repeatedly as it reaches desired temp. Use a meat thermometer and test for doneness in center near the bone but without touching the bone. Remove steak from pan a few degrees before done and let rest. Wipe out the skillet with a paper towel to remove any blackened bits and start the Sweet Corn Hash.
