One of the significant features of Masago is that it is smaller than most fish eggs – its diameter is about 1 millimeter. Masago roe naturally has a dull yellow color. To make it more visually appealing, it is usually dyed orange, red, green, or black colors, which gives it a more vibrant look. 

In this article, we will cover all relevant information about Masago. Read on and learn more about the taste, uses, and health benefits of Masago, as well as some popular recipes in which you can include this tasty ingredient.

Masago – Where Exactly Does It Come From?

Masago, also known as smelt roe, is a type of fish egg that comes from the fish species capelin. These small forage fish have silvery-green bodies, which makes them similar to sardines. Capelin are commonly enjoyed as a staple food in such species as the Atlantic cod, harp seals, codfish, seals, whales, and seabirds.

Capelin fish are sought after to create various products, including Masago. The meat of capelin is rarely consumed – over 70% of caught fish is used for fish meals and fish oil products. The remaining 30% is dedicated to producing Masago. 

The fish roe is harvested from female capelin once they begin spawning eggs, between two to four years old. The roe is harvested when the fish is full of ripened eggs but before the spawning stage.

Masago vs. Tobiko

Both are types of fish roe commonly used in many sushi rolls recipes. While Masago is capelin roe, Tobiko is flying fish roe. Both varieties are quite similar, however, Masago is slightly smaller and less crunchy than Tobiko. 

A significant difference between them is that Masago is much cheaper than Tobiko roe and many restaurants often use it as a substitute for Tobiko in various dishes. 

Masago vs. Ikura

Ikura is another variety of fish roe. It is harvested from salmon and is much larger than Masago. Also, when you eat Ikura, it bursts in your mouth as you bite into them, while Masago is slightly crunchy. 

What Does Masago Taste Like?

Similarly to other varieties of fish eggs, Masago has a subtly fishy flavor with a bit of saltiness. You can also detect some delicate sweet notes with a bit of a citrusy quality.

Its slightly crunchy and sandy texture makes it a perfect addition to rice dishes, vegetables, and many more. While the ingredient tends to have a relatively mild flavor, many Masago lovers like to mix it with various distinctive-taste ingredients, such as wasabi, ginger, or squid ink. Such combinations provide a stronger and more heightened taste for many dishes. 

What Is Masago Used For?

Thanks to its distinctive look and taste, the ingredient is commonly used as a topping in various sushi or nigiri recipes. It gives the traditional Japanese dishes some additional flavor and texture, as well as a pop of color for visual satisfaction.

Masago is often used in various seafood dishes to boost their flavor profile. Similarly, it is added to sauces and dips, too. 

Common ways of using Masago include:

  • As Masago sauce. Masago is mixed with light cream, soy sauce, or wasabi to create a creamy and delicious sauce. It is often added to Japanese spaghetti noodles. 
  • In fillings inside sushi rolls. Masago is sometimes added to the fillings when rolling maki sushi. It provides some extra flavor and crunchy texture.
  • In poke bowls. Masago is a perfect addition to fish and rice Hawaiian poke bowls as it elevates the fishy taste of the dish.
  • As decorations. Thanks to its bright, vivid color, Masago is often used as a decoration to enhance the look of many dishes. 

What Are the Health Benefits of Masago?

Masago is low in calories (40 calories per 1 ounce) and mercury levels, and it’s packed with many important nutrients. It is a great source of omega-3 fatty acids, vitamin B12, selenium, and magnesium. It is very high in vitamin D, which helps combat fatigue, insomnia, anxiety, or depression. The ingredient also contains polyunsaturated fats, which are good for your heart, hormones, lungs, and your immune system. 

Just 1 ounce of Masago contains 6 grams of protein, 2 grams of fat, and under 1 gram of carbohydrates. The same amount also covers 6% of the daily value for folate, 7% of the daily value for vitamin C, 10% of the daily value for vitamin E, 12% of the daily value for vitamin B2, and 16% of the daily value for selenium. 

What’s more, Masago, as well as other types of fish roe, is full of amino acids, such as valine, lysine, leucine, isoleucine, and phenylalanine. They are essential for repairing muscle tissue and protein synthesis.

What Are the Potential Risks of Eating Masago?

While Masago has many health benefits, there are also some drawbacks to it. For example, Masago is high in sodium – only one tablespoon of fish eggs contains around 10% of the daily value recommended for sodium which may be harmful to your health.

Too much sodium can lead to bone deterioration, kidney disease, and stomach cancer. Due to the high levels of sodium, Masago is not a good option for people suffering from high blood pressure or heart complications.

What’s more, Masago can cause allergic reactions, especially in those with seafood allergies. Therefore, you should always take special precautions before you eat Masago or serve it to others. 

While Masago is a relatively healthy and nutritious food ingredient, it is often mixed with components that are not healthy, especially in sushi recipes. Many of those components contain harmful factors, such as refined carbohydrates, that can lead to various diseases associated with consuming contaminated foods. 

Still, Masago is regarded as a healthy food option for a variety of dishes. Consuming it in small doses will let you enjoy its unique flavor along with vital health benefits. 

Is Masago Safe To Eat?

Shortly speaking – yes, Masago is safe to eat, although it often stirs up mixed feelings, just like other popular seafood products.

As Masago is consumed raw, many people may be put off straight away. Still, there is no evidence suggesting that eating Masago raw poses health risks.

It is a healthy and nutritious ingredient if eaten in moderation, and the only people who should avoid it are those allergic to seafood and shellfish. What’s more, fish roe contains vitellogenin, which is a type of egg yolk protein, that can also cause allergic reactions. 

Where Can You Buy Masago?

You can find Masago at many Asian or Japanese grocery stores or premium supermarkets, such as Whole Foods. 

If you do not have access to such stores in your area, you can also buy Masago online, for example, on Amazon. 

How To Store Masago?

To store fresh Masago, the best way is to either refrigerate it for immediate use or freeze it so that it can last longer. 

If you want to refrigerate it, keep the product in its original packaging and store it in the fridge for up to 5 days. This is the best option if you want to use it straight away, as you will not have to let it thaw.

However, if you’re planning to use Masago after the period of 5 days, freezing it will be a more suitable method. If you freeze roe, it can stay good for up to six months. Before using it, make sure to give it some time to thaw.
