Got some filtet mignon on sale at Costco for the same price as sirloin and ribeye. So I made a marinade and let it sit in the fridge for a couple of days. I set it out to come to room temp. About 3 hours. Put the grill and cast iron griddle on. Put it on high, let it come to about 600 deg air temp, about 950 griddle temp. 5 minutes a side and boom.
Sofa king good. Crust is perfect and interior is perfectly rare.
I still prefer the strip lol
