If you’ve eaten sushi you’ve likely already seen or tried tobiko. It’s used to add color and a crunchy texture to many sushi rolls,

This post is dedicated to all things tobiko. Learn about the species used, different types of tobiko, flavor profiles, sustainability, and more.

What is Tobiko?

Tobiko (とびこ) is the roe of flying fish. It’s often dyed and flavored. There are dozens of species of flying fish, of which several are popular for their roe. Tobiko is small, orange, and has a snappy texture. The flavor is naturally mild and briny.

The word tobiko is a shortening of “tobiuo no ko,” or “flying fish eggs.”

Tobiko is especially popular in the West. It’s served on its own as gunkan-style sushi and used as a garnish on top of nigiri and chirashi. But most Americans will be familiar with tobiko from its use on California rolls and other types of uramaki.

Flying Fish

Flying fish are generally fish of the open ocean and are most often found in tropical and subtropical waters. They feed primarily on zooplankton. Notably, flying fish have developed the ability to glide in the air to escape predation.

What Does Tobiko Taste Like?

Tobiko has a crunchy texture with a satisfying pop. They have a mildly sweet and briny flavor. Tobiko also tends to have a citrusy taste similar to orange zest.

Additionally, most commercial examples of tobiko are cured with sake vinegar and mirin. The sweet-sour rice flavors of these ingredients don’t overpower the roe, however.

Dashi or dashi extract is also commonly used for curing commercially available tobiko. This adds umami and a subtle smoky flavor.

Types of Tobiko

High-end, fresh tobiko will usually be cured simply in salt. This will have a light golden color and a sweet-briny flavor.

But the vast majority of tobiko one will encounter are processed with many more ingredients than simply salt.

A variety of commercial flying fish roe types of been popularized. They can be differentiated by color and usually have an added ingredient or two that makes them taste and look somewhat different.

As mentioned previously, most commercial examples of tobiko will contain sake vinegar and mirin. Soy sauce, salt, and sugar are also commonly used for curing. Preservatives and food coloring are also standard ingredients. And lastly, some commercial examples of flying fish roe will contain dashi or dashi extract.

Black Tobiko

Black tobiko gets some of its inky appearance from squid ink. This type of flying fish roe has a similar flavor to other commercial varieties, but a bit more umami and a flavor similar to octopus. Black tobiko also has a mild nutty and bitter taste.

Some commercial varieties of yellow tobiko use ginger, as well.

Like other commercial types of flying fish eggs, yellow tobiko is usually cured with some combination of salt, sugar (or fructose), mirin, rice wine vinegar, and soy sauce. Dashi or dashi extract is also common.

It’s easy to find at Japanese restaurants. But if you’re making sushi at home, your best bets are Asian grocers or online.

Some Japanese markets sell frozen masago and/or tobiko. Uwajimaya and Mitsuwa are two chains worth checking out. High-end seafood markets are also worth a shot.

But for most of the country, shopping online is the easiest, cheapest, and fastest way to buy tobiko.

Comparable Roe

Tobiko is most similar to masago and ebiko. Masago, which is smelt roe, is almost as common as tobiko, and is sometimes used as a substitute.

Though they appear similar superficially, tobiko is probably a little superior to masago. Why? It has a richer color, a firmer texture, and more flavor. Tobiko is also slightly larger. Learn more about masago vs tobiko here.

Ebiko is shrimp roe. It’s much more common in Japan than in North America. But it’s somewhat similar to tobiko in appearance, flavor, and texture.

Finally, salmon roe (ikura) is another fish egg often available at the sushi bar. Regardless of the salmon species, ikura is much bigger than tobiko. Ikura also has a softer, gooey texture with way more salty umami.

Occasionally, you might find sturgeon roe, or caviar, at high-end Japanese restaurants. The texture of sturgeon eggs is softer, their appearance is opaque and dark, and they have a fuller flavor. Like salmon roe, many types of sturgeon roe exist. But overall, they’re much more expensive than tobiko and masago.

Serving Tobiko

Both flying fish and capelin roe are popular as sushi and used in several similar ways.

Tobiko Sushi

The most common way tobiko is used in sushi restaurants is on the outside of uramaki. The California roll is the most famous of these inside-out rolls and helped popularize tobiko in the West.

You’ll also often find tobiko placed on top of nigiri as a colorful garnish. And it’s also commonly used on chirashi sushi.

Gunkan tobiko isn’t commonly served at high-end sushi restaurants in Japan. However, tobiko sushi is popular at more modest sushi restaurants and izakayas.

Other Ways to Enjoy Flying Fish

Tobiko makes a great addition to pasta and salads.

They also can be used as garnishes and to add color to many western dishes. They look especially good on top of raw oysters. Similarly, tobiko and masago sometimes find their way into oyster shooters. However, ikura is more commonly used for this purpose.

Tobiko Sushi Drink Pairings

There are many types of alcoholic beverages that pair well with tobiko and masago. These beverage pairings focus specifically on these fish roes. So the pairings work best with gunkan and sashimi presentations of tobiko and masago.

Pairing Flying Fish Roe with Sake and Beer

Sake makes a delicious pairing with both masago and tobiko. Look for sake styles that aren’t too rich or earthy and you’re good to go.

Sparkling sake, which often has some sweetness, makes for an excellent pairing too. The sweet ricey flavors marry with the salty-sweet umami of the fish roe. The bubbles and acidity then work to cleanse the palate.

Beer and fish roe can be a good pairing if the beer isn’t too strong. Lighter lagers like Sapporo Premium and Asahi Super Dry fit the bill. German Pils and Czech Pilsner are more flavorful than those Japanese beers but will still taste great with masago and tobiko. If you can find it, the subtly smoked Schlenkerla Helles rauchbier is outstanding with tobiko.

Wine Pairings with Tobiko

Fruity sparkling wine is also a nice pairing choice for the same reason that sparkling sake works so well. Prosecco is an especially a good option. Moscato d’Asti is a good choice too, and it really shines with wasabi tobiko and masago.

Dry sparkling wines like Cava and Champagne also make an elegant and refreshing pairing with most types of fish roe.

Still white wines often pair well with flying fish and smelt roe. This is especially true if they have briny or mineral elements, and also with wines that have some residual sugar.

Muscadet, Chablis, and Santorini Assyrtiko are delicious examples of the former. Demi-sec Vouvray and some Pinot Gris are examples of the latter. And German Kabinett Reisling has a little of both.

As a bonus, all of these wines work with a ton of other dishes you’ll find in a Japanese restaurant.

Recommended Shochu Pairings

Lastly, vodka and caviar is a classic pairing. A Japanese twist on this idea that works well is honkaku rice or barley shochu. It’s best to stick to shochu which’s between 20-24% ABV. Brands like Iichiko Silhouette, Kawabe, and Hakutake Shiro are great choices to pair with tobiko and masago as gunkanmaki.

Dietary and Nutritional Information

Tobiko and masago are both nutrient-rich, and they’re low in calories and carbs. Both are loaded with healthy fats like Omega-3 fatty acids. They’re also high in protein and minerals.

Masago and tobiko are both rich in vitamins. Vitamin B12 levels are especially high. Vitamin C and E levels are also somewhat high.

Mercury levels for both types of fish eggs are also much lower than larger predatory fish like tuna and mackerel.

The major downside of masago and tobiko is high levels of sodium. The use of salt, and sometimes soy sauce, only adds to their sodium levels.

High fructose corn syrup is also commonly used for processing masago.

Is Tobiko Gluten Free?

Naturally, both tobiko and masago contain no gluten. However, many commercially available examples of these fish roes use some soy sauce for curing. Soy sauce is not gluten-free, so be sure to check the label or ask the chef about the ingredients list.

Proper Storage of Tobiko

Tobiko and masago both freeze well and don’t lose their texture and flavor. Once thawed, keep them refrigerated. They’ll taste best within 3 or 4 days.

Sustainability

Both of these fish have multiple species, commercial uses, and fisheries across the globe. Pinpointing an exact answer is challenging, but we can get you close.

Is Tobiko Sustainable?

There are dozens of species of flying fish located across the globe. The fish themselves are often eaten, and their eggs are popular as tobiko. Different fisheries exist for the adults and for the eggs.

Overall, the practice of harvesting eggs limits the size of future generations of flying fish. The populations near Taiwan, southern Japan, and the East China Sea are considered healthy. But they’re susceptible to overfishing.
