The 2 Types Of Fat You Need For Perfect Ahi Tuna Steaks - Tasting Table
Briefly

The perfect ahi tuna steak is all about balance. The exterior is seared to form a crust, from golden to crispy, while the interior should remain rare or medium-rare.
Choosing a good cut of tuna is critical, as a cut that is too thin will lead to an overdone and dry interior by the time the exterior has seared.
Marinating your tuna can enhance flavor, but it's essential to monitor the marination time carefully to avoid cooking the fish with citrus too long.
Ensure your pan is hot before cooking. Your oil and butter combination should be near its smoke point for an ideal sear, which takes about 45-60 seconds per side.
