About "Whale Tail Meat Sashimi and Red Meat Tatsuta-age & Tatsuta-yaki"

Introducing three dishes using whale tail meat (Onomi) and red meat. Tail meat is an ultra-rare cut featuring fine marbling that surpasses fatty tuna, served here as sashimi. The red meat is marinated in a golden ratio of 6 parts mirin to 4 parts dark soy sauce and prepared as Tatsuta-yaki (pan-fried) and Tatsuta-age (deep-fried). The secret to keeping it juicy is residual heat cooking and avoiding overcooking.

Tips for Making "Whale Tail Meat Sashimi and Red Meat Tatsuta-age & Tatsuta-yaki"

Prep
- Since the tail meat is for sashimi, carefully wipe off any excess moisture with paper towels.
Seasoning
- For the red meat marinade, use a golden ratio of 6 parts mirin to 4 parts dark soy sauce with plenty of garlic and ginger. Marinate for 5 to 6 minutes to eliminate any gamey odor.
Heat control
- For Tatsuta-yaki and Tatsuta-age, sear or fry the surface quickly over high heat, then immediately turn off the heat and let the residual heat cook it through. Overcooking will make the whale meat tough.
Coating
- Blending equal parts of rice flour and all-purpose flour for the Tatsuta-age coating yields a wonderfully crispy texture.
Temperature
- Deep-fry the Tatsuta-age in oil heated to 170°C (340°F).

Food Science

Why This Dish Tastes So Good

The combination of inosinate, which is abundant in whale meat, and glutamate found in soy sauce creates a powerful synergistic umami effect. Additionally, during the cooking process of Tatsuta-age and Tatsuta-yaki, the Maillard reaction—occurring between the sugars in the seasonings and the amino acids in the meat—enhances the savory, aromatic flavor. Furthermore, the acidity of the sudachi citrus helps neutralize any gamey odors and brightens the overall flavor profile of the dishes.

Special Guest & the New Whaling Ship Kangei Maru

A unique guest dressed head-to-toe like a whale joins Iron Chef Rokusaburo Michiba. It is Hideki Tokoro, president of Kyodo Senpaku, a leader in Japanese whaling. President Tokoro passionately discusses the state-of-the-art mother ship Kangei Maru, launched in March 2024. This massive vessel boasts a gross tonnage of 9,299 tons, a length of 112.6 meters, and a width of 21 meters. Its key feature is an electric propulsion system powered by four generators and two motors, replacing traditional large engines. This design lowers the ship's internal height and flattens the slipway slope, allowing larger whales to be pulled up smoothly and processed quickly on board.

Whale Food Culture and Rare Cuts

Michiba reminisces about his youth when cuts like Onomi (tail meat), Kawa-kujira (skin), and Obake (tail fin) were common in restaurants. Obake, thinly sliced and tossed in vinegared miso, was even enjoyed at home during celebrations. On the table are today's rare cuts: premium marbled Onomi, deep red red meat, Saezuri (tongue), and intestines as thick as a human arm. The tongue is fattier, more tender, and richer in flavor than beef tongue. President Tokoro shares his passion for introducing the deliciousness of whale to younger generations to preserve this culinary heritage.

Today's Menu and a Creative Octopus Alternative

Michiba elegantly brushes today's menu: Onomi Sashimi, Red Meat Tatsuta-age & Tatsuta-yaki, Obake in White Miso, Saezuri Salad, and Intestines with Mustard Miso (Nuta)—a luxurious all-whale feast. In the kitchen, another guest, Jun Kuroda from T.O. Shokken, is introduced. To address the global shortage and soaring prices of octopus, Kuroda proposes "Whale Takoyaki" using whale tongue, sausage, and canned Yamato-ni (sweet soy-stewed whale). The Iron Chef is highly intrigued by this innovative idea to substitute octopus with whale for home takoyaki parties.

Premium Tail Meat Surpassing Fatty Tuna

The first dish is sashimi made from Onomi (tail meat), the most premium cut of whale. Located from the dorsal fin to the base of the tail, this muscle gets intense exercise, resulting in exquisite marbling. It is incredibly rare, accounting for only 1/2000th of the whale's total weight, and can fetch over 20,000 to 30,000 yen per kilogram. After patting off excess moisture, Michiba uses his signature "Roku-to" knife to slice the beautifully marbled meat. He arranges it over shredded daikon radish, serving it with grated garlic and grated ginger. Pairing it with Tosa soy sauce maximizes the rich fat and deep umami.

Secret Mirin-Soy Marinade for Red Meat

Next is the preparation of red meat, a classic cut from the back, belly, or chest. It has little gristle, is reasonably priced, and is easy to handle. Michiba shares a poetic story about how Tatsuta-age gets its name from the autumn leaves of the Tatsuta River in Nara. For the marinade, he uses his signature "mirin-soy" sauce, combining mirin and dark soy sauce in a 6:4 golden ratio with plenty of grated garlic and grated ginger. Marinating the bite-sized red meat in this special sauce for 5 to 6 minutes is crucial for removing any gamey odor and unlocking the meat's deep flavor.

Tender Tatsuta-yaki via Residual Heat

Using the marinated red meat, Michiba first prepares Tatsuta-yaki. He heats a small amount of oil in a pan and adds the meat. The ultimate secret he shares is not to overcook it. After searing the surface quickly over high heat, he immediately turns off the flame and lets the residual heat cook it through. This keeps the meat incredibly juicy and tender. Michiba then suggests a "Tatsuta-yaki Sandwich" by lightly frying small pieces of sliced bread and sandwiching the seared meat. President Tokoro is thrilled by this novel idea, which beautifully fuses Japanese technique with Western ingredients.

Crispy Tatsuta-age and Its Health Benefits

Next, the remaining red meat is used for the classic Tatsuta-age. After lightly draining the marinade, the meat is coated. Michiba's secret is using a special 50:50 blend of rice flour and all-purpose flour. He coats the meat thinly and evenly, then deep-fries it in oil heated to 170°C (340°F). Again, avoiding over-frying is key; remove it as soon as the outside is crispy. Meanwhile, President Tokoro explains the benefits of balenine, a powerful fatigue-recovery compound abundant in whale meat. It enables whales to swim thousands of kilometers without eating, and is studied for human fatigue recovery, dementia prevention, and anti-depressant effects.

Tasting: Melting Tail Meat & Juicy Tatsuta

Finally, it's time to taste. They start with the Onomi sashimi. The moment they dip it in soy sauce and eat, everyone exclaims in delight. The finely marbled fat melts instantly, spreading an elegant flavor that surpasses even fatty tuna. Next, they try the Tatsuta-age and Tatsuta-yaki. The residual-heat-cooked Tatsuta-yaki is incredibly tender and juicy. The Tatsuta-yaki Sandwich made with fried bread is a masterpiece, offering a perfect contrast of crispy bread and tender meat that stays soft even when cold. Praised as a flavor kids would love, the feast showcases the endless potential of whale meat and the Iron Chef's mastery.
