What Is Masago Exactly?

The Origins of Masago

Masago (まさご) is the Japanese term for capelin roe, harvested from the small smelt-like fish known as Mallotus villosus. Capelin thrive in the icy waters near Iceland, Norway, and Canada, and their roe is prized for its subtle crunch and mild ocean flavor.

In Japanese cuisine, masago is used both for its visual appeal and its taste-enhancing quality. The eggs are tiny, soft, and slightly salty perfect for rolling onto sushi or sprinkling over rice dishes.

Masago vs. Other Fish Eggs

Unlike luxury caviar or flying fish roe (tobiko), masago is more affordable and milder in flavor. It’s often dyed with natural colorants orange, black, green, or red to match different sushi aesthetics and flavors such as wasabi, squid ink, or chili.

Masago in Japanese Cuisine

A Beloved Ingredient with Many Roles

In Japanese cooking, masago isn’t just decoration, it’s a versatile element that enhances umami and texture. It appears in sushi rolls, sauces, and even fusion dishes.

Common Culinary Uses of Masago

• Masago Sushi Rolls: California rolls, spicy tuna rolls, or dragon rolls often feature masago on top for crunch and color.
• Masago Mayo Sauce: A creamy condiment blending mayonnaise, masago, and soy sauce drizzled over sushi or poke bowls.
• Masago Nigiri: A small bed of sushi rice wrapped in seaweed, topped with bright masago pearls.
• Seafood Garnish: Sprinkled over grilled fish or rice bowls to add a savory oceanic pop.

Masago is favored for its mild taste and soft texture, which complements delicate ingredients like avocado, cucumber, or salmon.

How Masago Is Harvested and Processed

From Ocean to Sushi Bar

Masago’s production begins when female capelin are caught during their short spawning season. The roe is carefully extracted, cleaned, and cured with salt. This preservation step enhances flavor and shelf life.

After curing, the roe may be:

• Colored using natural dyes to produce orange, black, or green varieties.
• Flavored with ingredients like wasabi or chili.
• Frozen to maintain freshness until it reaches restaurants.

Most of the world’s masago supply comes from Icelandic and Norwegian fisheries that follow sustainable harvesting practices.

Tobiko vs. Masago: What’s the Difference?

Visual and Taste Comparison

People often confuse tobiko (flying fish roe) and masago (capelin roe), but they differ in several key ways:

Feature	Masago	Tobiko
Source	Capelin fish	Flying fish
Egg Size	Small, smooth	Larger, crunchy
Flavor	Mild and slightly salty	Rich, smoky, and bold
Color	Pale orange (can be dyed)	Naturally bright orange
Texture	Soft and creamy	Firm and popping
Price	More affordable	Higher-end

Culinary Preference

Chefs may choose masago when they want a delicate flavor that blends seamlessly into sauces or rice, while tobiko is preferred for visual drama and a stronger bite. Masago also serves as a budget-friendly alternative in many sushi establishments.
