I am getting better with my Ahi Tuna, I have a container of dry rub that was given to me at OutBack Rest.

I freeze the Ahi Tuna, once frozen I set it out, let it thaw just enough for the dry rub to stick

cover bottom of skillet with Olive oil and sear on both sides for 30 seconds

place in refrigerator for 3-4 hours then slice
