Ok...my son and I tried this tonight and it was awesome.
Season sirloin heavily with kosher salt, pepper, onion powder, garlic powder, rosemary and basil.
Sear at on top of stove then cook in over till 125-130. Make it as rare as you can like.
I served it with a Creme fraiche horse radish sauce. But, my son loved it without.
Dang it it was good with a nice Merlot.
I think I got the picture figured out.
