Kindai Tuna Demo and Tasting

Early last week, I was lured into the French Culinary Institute in SoHo by sweet promises of freshly sliced sashimi and a chance to witness a masterful dissection of a tuna.  Curious and hungry culinary students and professional chefs evidently fell for the bait too, filling up the seats in the small auditorium to witness the artful slicing and deconstructing of Kindai tuna by Chef Toshio Suzuki of Sushi Zen, Chef Noriyuki Kobayashi of Megu and Chef Kazuhiro Sato of Poke.

Kindai tuna is born and raised at Kinki University in Higashi-Osaka, Japan.  Born in the laboratory and hand fed wild catch, they are raised in better conditions than other farm-raised tuna and offer a more sustainable alternative to wild bluefin tuna.

The introduction of the lecture was led by Nick Sakagami, who described Kindai tuna as “couch potatoes” in comparison to their “athletic” wild counterparts.  Less active and therefore subsisting on less mercury-laden wild catch, the mercury levels in Kindai tuna are only .6 parts per million, while wild tuna often have levels of 1 to 2 parts per million.

Organized by the Gohan Society, this demonstration was a rare opportunity to taste Kindai tuna.  Raising tuna by these methods is pricey–about 200 Kindai tuna are successfully raised every year and only 1 to 2 fish shipped to the United States every week.

Official Kindai Tuna Seal

The official Kindai Tuna seal of approval indicates and ensures that the has been raised at Kinki University.  Now, for the cutting of the tuna!

We watched as the three chefs wrestled the fish and skillfully attacked it with an artillery of sharp knives.  First, an incision was made along the side of the fish, then through the gill to take off the head with a long square-shaped knife.  The rest was then cut up into more manageable segments, using smaller, precise knives, and laid aside to be carefully sliced into fillets later on.



Since the fish is killed by stunning it with electricity, there is often some bleeding near the spine–that part is sliced away by Chef Suzuki and saved to be cooked later on.  Electric shock is a common slaughtering technique used to quickly stun and kill fish.

Some more slicing.

Sampling different parts of the tuna

Small tasting plates of tuna were passed around for everyone to try, each bite-sized piece a different gradient of pink and from a different part of the fish.  The buttery “oh toro” and “chu toro” differed slightly in fattiness, but both were equally delicious and smooth.  The leaner “akami” and “hakaochi” had a gamier taste and buoyant texture, while the small spoonful of “assorted scrape” burst with a bright punch of citrus and a hint of onion flavor from the thin scallion shavings.  (Check out the plating cheat sheet below for some proper Japanese tuna terminology)

Plating cliff notes

The correct way to eat sashimi, especially with freshly grated wasabi, is the double-dipping method.  First dip one side of the fish generously in the wasabi, then follow through with a second dip into the soy sauce, gliding the portion of the fish that has not come in contact with the wasabi quickly across the pool of soy sauce–be careful as to not submerge the whole piece.  This method preserves the spicy, subtle taste of wasabi without being muddled by the saltiness of the soy sauce.  According to Chef Suzuki, mixing together soy sauce with fresh wasabi overpowers and ruins the wasabi flavor.  Unlike the spicy green goop you find at cheaper sushi places that is usually made from a powder, fresh wasabi has a lighter, refreshingly pungent flavor, since it is not mixed in with horseradish or other fillers.

The bigger slabs are pared down into clean, long rectangular slabs, ready to be sliced into sashimi-sized slivers.

Cooked tuna vertebrae

Second round of tasting was cooked tuna. Little white ceramic bowls containing chunks of broiled tuna with caramelized onions were passed around for us to try.  Midway through our tuna, Chef Kobayashi emerged from the kitchen with a tray of tuna spines and asks, “Sorry there is not enough for everyone, but who wants to try?”.  Luckily, I was one of the few who looked eager enough to deserve a taste of broiled tuna spine.  The spine was cut up into individual vertebrae, each a tiny shot of briny cartilage topped with a sprinkling of sesame seeds and chopped scallions.  The meat surrounding each vertebrae charred to a smoky perfection and packed with flavor from the bone.

Chef Kobayashi extracts the eyeballs with a sharp knife.

tuna brains

Broiled tuna brain (above) tasted surprisingly similar to the meat of the fish, except with a denser texture and richer flavor.

tuna cartilige

For the more adventurous eaters, chunks of freshly cut vertebrae were passed around.  It was more gelatinous and gooey than the cooked version but meatier around the bone.  After slurping up the cartilage I proceeded to gnaw the meat off the bone.

Eyeballs and collar

Although only certain parts of the fish are eaten raw, sashimi-style, none of it goes to waste.  It may look like a gruesome murder scene from a Quentin Tarantino movie, but the collar, eyes, and brain are cooked and made into other delicious tuna dishes.

tuna scrapings

Even the fatty scrapings from the skin of the tuna are used to as filling for maki rolls.

At the end of the demonstration, slabs of tuna were sold, individually wrapped in plastic and packed into iced bags for those who wanted to bring tuna home for dinner. After my $30 worth of medium-fatty tuna was all weighed and paid for, I snuck into the kitchen sweetly asked one of the chefs for some fresh wasabi.  A quick glance and a nod later, I was out the door and on my way home, with wasabi and tuna in tow.

    I am extremely jealous, this demonstration looks amazing.

    • veronica says:

      it was quite amazing, and those knives are like samurai swords. if you look at the last photo, the photographer on the right is holding the knife and looking at it in complete awe

  2. Veronica,
    A tremendous chronicle…..and really great pics. Well done indeed. I feel like I was there.

    And like the many who were not, am regretting it immensely.

    Kudos to Mika Higurashi and Sona Seafood as well as to Nick Sakagami for bringing this amazing product to the East Coast.

    A sustainable tuna, from egg to plate, is a wonderful step in the right direction for sustainability overall and it will relieve some pressure on wild bluefins.

    It may be expensive, but it is worth it and let us support these efforts with our pockets as well as our praise.

    I missed the opportunity to join you as per invitation from Nick, and feel you wrote and covered this even with great precision! Thank you for sharing, and if you do not mind I would like to feature your piece along with updates from Nick via email on my blog. -E

    dar! I wish I’d know about this. I’m really interested in Tuna, esp Kindai and sustainability… Can you let me know if you see any tuna events come up?

    • Veronica says:

      If I hear about future Kindai tuna events I’ll def let you know! I was at the seafood show in Boston earlier this year and it was interesting to learn more about seafood sustainability, but it’s too bad most of the tastier fishes are the unsustainable ones

  5. Hi – I don’t comment on many web sites but had to on your site. It’s fantastic! I really like how you write – very to the point, unlike a lot of other blogs. Thanks for having this site. I found your site while looking for another one on Google. I don’t have time to read all the recipes right now, but I have bookmarked the home page and will visit again very soon to see your latest updates. I love reading about cooking, it is my favorite past-time. The recipes on your site are incredible. I can’t wait to try them out on my family. They think I’m crazy (and maybe they are right lol) when they see me at work in the kitchen. Click here if you’d like to check out my site. Keep up the great work!
