Toro (sushi)

Toro (トロ) is the fatty meat of tuna served as sushi or sashimi. It is usually cut from the belly or outer layers of the Pacific bluefin tuna (the other fish known for similar meat is bigeye tuna). Good-quality toro is said to create a "melting" sensation once placed in the mouth.

The cut is very desirable and has the highest price in the areas of the world where consumers like fatty fish (Japan, USA). This preference is a relatively new phenomenon: prior to the Second World War toro was considered to be of low value and frequently simply discarded.

Toro is subdivided into two grades:
 * Ōtoro (大トロ) – very fatty cut from the area belly area just behind the head, tender and rich; expensive and usually served on special occasions;
 * Chūtoro (中トロ) – less fatty cut made from the areas closer to the tail; the fat content in the case of bigeye reaches 25%.

The meat from the inner layers of the fish, called akami (赤身), is more reddish and has less fat (with 14% fat in bigeye).

Toro from wild tuna is a seasonal product: winter tuna is considered to be better, summer one is less fatty.
