Good to Know
Fresh steaks at the counter should smell clean like the ocean, never fishy, with firm flesh and a deep red or pink color. Seared rare to medium keeps it from drying out, since this cut has almost no fat to protect it during cooking. Restaurant versions are where carbs sneak in: teriyaki glazes, sesame-soy marinades, and sweet ahi poke sauces can add several grams of sugar, so ask how the fish is seasoned or stick to a simple salt, pepper, and oil prep at home.
