Cuts of Bluefin Tuna

AKIMI - The Prime Cut Par Excellence

Akimi is the most commonly used cut of tuna and is cut from the loin. It is low fat, high protein and healthy. It is better for raw preparations such as tartar and nigiri.

TORO - Fatty Tuna

Toro the fatty part of the tuna that comes from around the belly of the fish. It has a soft texture and melts in the mouth. It is the most expensive part of the tuna; each fish offers only a minimal quantity.

The toro is split into two parts Otoro - the most highly prized and Chutoro.

Chutoro is the belly area known for its medium fatty quality ad the middle part between the Otoro and Akimi. Chu means 'middle' in Japanese; it is not too fatty nor too lean. It is similar to the Akimi with the addition of slight sweetness and a more pinkish colour graduating to deep red because of the higher level of fattiness at one end. The Chutoro is perfect for serving raw. As sashimi, sushi, tartar, ceviche or simply grilled or barbecued, the result is outstanding.

Otoro is the most prized and comes from the belly, which is the fattiest part of the tuna, The most legendary cut of tuna, and one of the most highly prized by lovers of fine cuisine. With a pinkish colour and silky, highly delicate texture, the belly, known as “Otoro”, is found at the base of the lower loin and contains the highest fat level. The undisputed star of raw dishes, such as sushi, tartar and sashimi, although its versatility also allows it to shine in other forms, such as grilled, barbecued or in a range of casseroles. Some chefs cook it to create a striking roasted crust.

Buying

Before buying, we inspect each Bluefin tuna as a whole fish to guarantee the flesh's freshness, grade and colour. Whole tunas are air freighted to London each week. We watch as the tuna is butchered into its main parts, then select only the premium parts of the belly and the loin. 

Preparing Bluefin Tuna

To offer the best quality fish, we blast freeze the tuna to -50°c. This process is essential to optimise the freshness of the meat, as fresh tuna flesh deteriorates very quickly. The freezing process kills off microorganisms, ensuring the tuna is perfectly safe to eat as a raw product.

The tuna is then transferred to storage at -60°c to preserve the colour and freshness of the fish and ensure no deterioration of the flesh takes place over time.  

To ensure optimal quality, it is advisable to remove the tuna from its packaging before defrosting. Placing it on a plate in the refrigerator is the preferred method, as this minimises the risk of liquid accumulation that may discolour the tuna if the packaging is retained. For the finest experience, it is recommended to use the tuna promptly, as extended storage in a home freezer may affect its colour. Although discoloured tuna remains suitable for consumption, for an unparalleled dining experience, we encourage using the tuna as soon as possible.
