Among the many varieties of fish used in sushi, some are better known than others. While tuna and salmon dominate most menus, there are hidden gems that offer distinct textures and flavors for the more curious palate. One of those underrated choices is Ono, a fish that is both delicate and rich in taste. Often overlooked but highly valued by sushi enthusiasts, Ono in sushi refers to a type of fish that delivers a buttery, clean bite with subtle sweetness. Understanding what Ono is and why it’s gaining popularity can enhance your appreciation for sushi as a diverse culinary experience.
What Is Ono in the Context of Sushi?
Definition and Identity
In sushi terminology, Ono refers to a fish known in English as Wahoo. It is a saltwater fish found in tropical and subtropical seas and is recognized for its elongated body and speed. The name ‘Ono’ is derived from the Hawaiian word for delicious, which already hints at the reason behind its inclusion in sushi. Though not as mainstream as tuna or yellowtail, Ono has a firm yet flaky texture and a clean, slightly sweet flavor that makes it well-suited for sushi and sashimi preparations.
Scientific Classification
Ono belongs to the mackerel family and is closely related to species like king mackerel and Spanish mackerel. Its scientific name isAcanthocybium solandri. In sushi bars, it may sometimes be listed as Wahoo or Hawaiian Ono. Despite its limited availability compared to other fish, it is prized for its lean flesh and versatility.
Flavor and Texture of Ono in Sushi
Clean and Mild Flavor Profile
One of the reasons chefs choose Ono for sushi is its subtle flavor. It is not overpowering or fishy, which makes it perfect for diners who prefer milder-tasting seafood. Its delicate sweetness complements the vinegared rice typically used in nigiri or rolls, creating a balanced mouthfeel with every bite.
Firm, Yet Tender Texture
Ono offers a satisfying firmness that holds its shape well when sliced thin for sushi. The meat is denser than tuna but less oily than mackerel, offering a texture that is somewhere between flaky and meaty. This makes it especially desirable in both raw and lightly seared preparations.
Common Sushi Preparations Using Ono
Ono Nigiri
In nigiri form, Ono is sliced into small fillets and placed atop seasoned sushi rice. The simplicity of this preparation allows the natural flavor of the fish to stand out. A light brush of soy sauce or a touch of wasabi is sometimes added to enhance the experience without overpowering the fish.
Ono Sashimi
For sashimi, Ono is served without rice, allowing diners to appreciate its texture and flavor more directly. Thin slices are arranged elegantly and may be accompanied by garnishes like grated daikon or citrus.
Ono Sushi Rolls
Though less common, Ono can be used in maki or uramaki rolls, often paired with ingredients like avocado, cucumber, or spicy mayo. These combinations bring out the subtle taste of the fish while adding creamy or crunchy textures to the roll.
Lightly Seared Ono (Aburi Style)
Some sushi chefs prefer to sear Ono lightly using a torch. This technique, known as aburi, caramelizes the surface of the fish while keeping the inside raw, enhancing its flavor with a smoky, umami-rich note.
Why Sushi Chefs Value Ono
Balance of Lean and Flavorful
Unlike some fatty fish that can become too rich or oily, Ono provides a lean but still flavorful option. Its mildness makes it easy to pair with a variety of other sushi toppings and seasonings.
Versatility in Use
Because of its firm structure, Ono is easy to work with when making precise sushi cuts. It can be served raw, seared, or even grilled without falling apart. Its adaptability makes it a favorite among creative sushi chefs looking for something unique but not too bold.
Appeal to Both Beginners and Connoisseurs
For those new to sushi, Ono provides an accessible introduction to raw fish without the strong flavors of something like sardine or mackerel. For more experienced diners, its rarity and clean taste offer a break from more common selections.
Nutritional Aspects of Ono Fish
High in Protein, Low in Fat
Ono is an excellent source of lean protein, making it a great option for health-conscious diners. It has a lower fat content compared to salmon or tuna, which also means fewer calories per serving while still being satisfying and nourishing.
Rich in Essential Nutrients
In addition to protein, Ono contains important nutrients such as:
- Vitamin B12
- Niacin (Vitamin B3)
- Selenium
- Phosphorus
These nutrients support energy metabolism, brain function, and overall cellular health, making Ono not only delicious but also beneficial.
Where to Find Ono Sushi
Availability in Sushi Restaurants
Not all sushi restaurants offer Ono due to its more limited supply. You are more likely to find it at high-end sushi bars or establishments that specialize in seasonal and specialty fish. In places with access to fresh Pacific seafood, such as California or Hawaii, Ono may appear more frequently on menus.
Ask for It by Name
If you’re curious to try Ono, it’s worth asking your local sushi chef or server if they carry it. Some places may have it listed under the name Wahoo, while others might include it as a chef’s special or part of an omakase (chef’s choice) menu.
