Bluefin Tuna - Otoro


Balfegó - Farm-Raised Mediterranean Bluefin Tuna Otoro Saku Block

Bluefin tuna, the most prestige and luxurious of all fish but when caught in the wild are also the most endangered.

Our Bluefin tuna is caught using the 'purse-seine' technique, a highly sustainable fishing method designed for the non-capture of smaller fish. It also allows for the reproductive activity of the tunas even after their capture. Fishing quotas are allocated by ICCAT, a world-wide regulatory authority. Furthermore, a portion of the generated income from the tuna is used to fund scientific research projects that directly support the sustainability of this prized species.

Balfego's pioneering traceability process enables individual identification and accreditation of every single tuna and its parts. For each piece of Bluefin tuna that they sell, Balfego has a full record of Microbiological analysis and fat content of the tuna and can trace the product all the way back to the sea. 

On top of offering a guarantee of quality, this system allows Balfego to certify that each piece of tuna has been captured according to regulation, which ensures the continuity of the species and proves that Grup Balfego acts within the frame of International organization-assigned quotas.

Cooks Tip: Otoro is the fattiest part of the tuna and because of their delicious fatty meat bluefin tuna loin is best served raw and thinly sliced for sashimi and sushi preparations. However, it can be very quickly seared in a hot pan on all sides, sliced and served 'tataki' style with fresh ginger, chilli and ponzu.

All of our tuna is carefully prepared here in the UK as soon as it is delivered. We then use an IQF freezing technique that brings the temperature down to -30° in approximately 3 minutes. This ensures that the fish you receive, once defrosted, will be in perfect condition and offer the same performance as a fresh fish. Seared tuna will be deep pink - to dark red in the centre and our tuna can also be used as sashimi or tartar.

Net: 250g

For the shipping fresh and frozen goods we use high quality mixed recyclable insulated packaging to keep your products perfect through the courier network.

To keep frozen goods at the correct temperature we use a safe alternative to dry ice.  These gel packs freeze to a temperature of -45° and stay frozen for an extended period of time. Completely food safe and fully recyclable/reusable.


The vast majority of shipments arrive frozen but we cannot guarantee this.  In the event that your order has defrosted it should still be at a very low temperature when you receive it and therefore fine to put in your freezer.  Refreezing is only unsafe if the product has reached 8°c. It is worth mentioning that supermarkets routinely sell defrosted food as "fresh", with the advice that it may be frozen when you get home.

All frozen products arrive in extremely high quality, fully insulated packaging.


All fresh truffles are sent in a foil resealable pack with an absorbent paper.  This is suitable for storing in your fridge.  If storing truffles for more than a few days we recommend wrapping them in paper towel or using a Tuberpac.  Fresh truffles are always best consumed as soon as possible.
