What Is Ahi Tuna?

Ahi tuna is a class of tuna typically found in tropical waters and is separated into two species: big eye and yellow fin. Ahi tuna texture and flavour closely resembles blue fin tuna and is preferred because it is less expensive than blue fin tuna.

Seared tuna steaks are very different from canned tuna. The whole ahi tuna is fabricated into a beautiful steak with a deeply rich color that holds its shape unlike other species of fish that are prone to flaking. Ahi is taking the world by storm because of its flavour and health benefits.

Health Benefits Of Ahi Tuna

Ahi tuna is rich in Omega 3 acids and vitamin B12. Omega 3 fatty acids play a crucial role in cell membranes all over the body and they influence the role of cell receptors in cell membranes. They act as a jump-off point for homes that control blood clotting, inflammation, and the contracting and relaxing of arterial walls.

Vitamin B12 is responsible for keeping your body's nerve and blood cells healthy in addition to the creation of DNA. Vitamin B12 is also responsible for stopping certain individuals from developing Megaloblastic anemia, a disease that drains people of their energy and makes them feel weak.

Is It Really Safe To Eat Raw Fish?

Raw Ahi Tuna is safe to eat, but if you prefer a well-done steak it is perfectly fine. Tuna steaks are generally served seared on the exterior and uncooked on the inside. Almost all ahi tuna steak recipes are cooked this way. Most restaurants cook ahi tuna steaks to medium-rare, but if you are still skeptical about raw fish you can request a well-done tuna steak. Keep in mind well-done tuna steaks can be a little dry similar to the canned stuff. When tuna steaks are cooked to medium-rare the outside develops a beautiful crispy salty delicious crust and an inside that is succulent, silky, and tender.

How To Cook Ahi Tuna Steaks

Because the steaks are cooked to medium-rare the cooking time is very fast. Marinate the tuna steaks in a delicious mix of olive oil, soy sauce, salt, and pepper. Marinate the steaks for at least 10 minutes or overnight so ahi can absorb all of those beautiful flavours.

Fish tends to cling to the surface of the pan, be sure to sear your steaks in a nonstick skillet or a seasoned cast iron skillet. Since ahi tuna steaks are usually 1 /2 inches thick it takes about two minutes to sear per side.

It is of the utmost importance to let the skillet get extremely hot before you add the fish to the pan. Place the pan over a medium-high flame for 4-5 minutes to ensure the pan is hot. This helps the outside of the fish to cook quickly while the inside of the steak remains raw. Let the steak rest for 5 minutes before slicing and you will have the perfect Ahi tuna steak that is crispy and delicious.

How To Thaw Ahi Tuna Steaks

Ahi tuna steaks can be thawed in the refrigerator. To thaw steaks in the fridge, place the tuna in the original vacuum-sealed package on a plate. Place the plate in the fridge and defrost for 24 hours. If the package's seal is broken, remove the fish from the covering and tightly wrap it in plastic wrap and transfer the plate to the refrigerator.
