Well, well. I just put a steak in a cast iron skillet that was so hot a drop of water disappeared immediately. I left the steak in the skillet for three minutes.
Then I turned it over and put it in a 500 degree pre-heated oven for 5 minutes.
I took it out, put it on the plate and covered it with foil and let it rest for 5 minutes.
I sliced it open and had steak tar-tar.
Now it’s back in the skillet and back in the oven. Bottom line is the directions didn’t work.
I hope you were able to enjoy dinner after you made it right.
