Masago: What is it?
Also known as ‘smelt roe,’ Masago is a type of edible fish egg that comes from the fish species capelin.
These fish are mostly found in the North Pacific, North Atlantic, and Arctic Oceans. Belonging to the smelt family of fish, the capelin is enjoyed as a staple food in species such as harp seals, codfish, seabirds, seals, whales, and the Atlantic cod.

With a small stature and a silvery-green body, capelin closely resembles sardines. But, unlike sardines, capelin are sought after to make various products such as Masago. In fact, over 70% of caught capelin is used for fish meals and fish oil products. The remaining 20% to 30% is used to produce Masago.
Although harvested for edible purposes, the meat of capelin is rarely consumed. Masago roe, however, is commonly used as the main ingredient in a range of traditional Japanese dishes.
Masago is harvested when the female capelin are full of eggs. However, this occurs before any spawning takes place. Once the eggs have been retrieved, they are mainly used as ingredients in sushi roll toppings. The eggs have a pale yellow tint to them but they are often dyed with bright, vivid colors such as red, orange, and green. This is to make dishes more interesting to look at.
What Does Masago Taste Like?
Masago has a sweet as well as savory flavor. They are popular as the small eggs provide an additional kick to most dishes.
As well as sushi recipes, Masago is often used in other seafood dishes and is commonly used to boost the flavor profile of various sauces and dips, too.
While it tends to have quite a mild flavor, Masago is sometimes mixed with other ingredients such as wasabi, ginger, and even squid ink to produce a stronger, more heightened taste for dishes.

Masago Health Drawbacks
Although there are many health benefits to Masago, there are also some drawbacks to the fish eggs. Firstly, Masago contains around 10 percent of the daily value recommended of sodium to an individual in just one tablespoon.
For those who suffer from heart complications or high blood pressure, Masago may not be the best option. Too much sodium can also lead to stomach cancer and bone deterioration.

Although Masago is relatively healthy on its own, it is often mixed with unhealthy ingredients, especially in sushi recipes. Many of these ingredients contain refined carbs and other harmful components that can lead to a risk of foodborne illnesses and parasitic infections.
In small doses, however, Masago is deemed to be a healthy food for a variety of dishes.
