there's been some speculation about my method. it was actually a type of hybrid Ducasse.
i set the burner just slightly above medium, and stood the steaks on the fatty edge for 1.5 minutes to let the fat render. then i cooked both steaks at the same time on medium for 10 minutes, flipping once a minute. by that time they had already started to build up a good crust. here's a picture of them resting before the sear.
i then cranked the heat up all the way, added vegetable oil. i let it smoke for a little longer than normal before putting the steaks back in, so pan was hotter. after adding the steaks, the pan flared up briefly, but i was able to get it under control. i seared for two minutes per side, and then seared each edge for about 30 seconds.
