Bluefin Tuna Flavor Profile
Bluefin Tuna has the darkest and fattiest flesh of all tuna. It has a distinctive medium-full flavor and firm, “meaty” texture with large flakes. It is best served as sushi or cooked rare to medium-rare. Over-cooked tuna is “dog food”…tough and tasteless like eating cardboard.
Tuna Grading is as follows: No. 1 “Sashimi-grade” is the best, being the freshest and having the highest fat content. No. 2 “Grill-grade” is next best. No. 3 and No. 4 are lesser quality.
Typical Cooking Methods
Giant Bluefin, Northern Bluefin, Atlantic Bluefin, Kuromaguro,Honmaguro, Toro
Average commercial weight is 200-400 Lbs, but Bluefin Tuna can reach over 2000 lbs and 12′ long. They have a blue-black upper body and silvery sides.
Storage & Handling Recommendations
Store fresh loins/steaks as close to 33° as possible to maintain highest quality and shelf life. Although ice can be used, the flesh should be tightly wrapped in plastic and placed in perforated pans. The flesh should never come in direct contact with ice or water as this will discolor the meat, leech the oil content, and decrease shelf-life. Tightly wrapping in plastic will also slow the natural oxidation of the meat color which fades from a bright color to a darker, more opaque color.
Range & Habitat
Bluefin Tuna are found between southern California and Japan, Northeastern US to Newfoundland, and Spain to the Mediterranean Sea.
