Take a Tuna filet and pat it dry. There must be no wetness on it. This is very important. Sprinkle salt and pepper on all sides of the Fish.
Heat oil and place the fish, skin side down. Four minutes later, turn it. Another four minutes and let it stand up like a Minhar from the Asterix comics. That’s for another three or four minutes.
This will drain all the oil and give you one more crispy side.
Rest for five minutes to enjoy a well done but not chewy tuna.
