What Is Masago? Healthy Benefits & Side Effects of Capelin Fish Roe

Masago, also known as capelin fish roe, is a popular ingredient in Japanese cuisine, especially sushi. These tiny, orange eggs not only enhance the visual appeal of dishes but also add a crunchy texture and a burst of umami flavor.

What Is Masago?

Masago, often seen as tiny orange pearls atop sushi rolls, is a delicacy cherished by seafood lovers. It’s the roe of the capelin fish, a small forage fish found in cold-water regions.

Origins And Source Of Masago

Masago comes from the capelin fish, scientifically known as Mallotus villosus. These fish thrive in the cold waters of the Atlantic and Pacific Oceans. The largest populations are found near Iceland, Norway, and Canada.

The capelin fish is known for its annual migrations to shallow coastal waters to spawn. During this period, fishermen harvest the roe. The demand for masago has led to sustainable fishing practices to ensure the capelin population remains healthy.

Here’s a quick overview of the regions where capelin are commonly found:

Region	Population Density
North Atlantic	High
North Pacific	Moderate
Arctic Ocean	Moderate

How Is Masago Made

The process of making masago involves several steps, ensuring the roe is clean and safe for consumption. Once the capelin fish are harvested, the roe is carefully extracted. This requires precision to prevent the eggs from bursting. The roe is then washed thoroughly to remove any impurities.

After cleaning, the masago is typically cured with salt and other seasonings to enhance its flavor and extend its shelf life. Common seasonings include soy sauce, sugar, and sometimes spices. This curing process not only flavors the roe but also gives it the distinctive orange color. Some manufacturers add natural colorants to achieve a more vibrant appearance.

Here’s a step-by-step breakdown of the masago production process:

Harvesting capelin fish during spawning season.
Extracting the roe with care.
Washing the roe to remove impurities.
Curing the roe with salt and seasonings.
Packaging the masago for distribution.
