Capelin Roe (Masago)

Tiny crunchy orange fish eggs that garnish sushi rolls and add briny pop.

Capelin roe, sold as masago, are the small eggs of the capelin smelt, naturally pale and usually dyed bright orange. They have a subtle briny flavor and a fine crunchy texture, used to coat and garnish sushi rolls and top rice bowls. Smaller and crunchier than tobiko, they are an affordable sushi-counter staple.

Masago is the roe of the capelin fish (Mallotus villosus), a small smelt relative harvested during spring spawning runs in cold Atlantic, Pacific, and Arctic waters. At 0.5–1.0 mm in diameter, these are among the smallest fish eggs used in cuisine, giving masago its characteristic slippery coating and barely-there crunch—distinctly softer and less distinct than tobiko. The natural orange-to-reddish hue comes from carotenoids in the capelin's diet, though most commercial masago is artificially colored for the wasabi (green) and spicy (red) varieties.

Masago is almost always pasteurized in brine and sold in small jars or tubs; once opened, use it within five to seven days. Japan dominates commercial production for sushi use, but Scandinavia has its own tradition where capelin roe appears more plainly on sourdough or blinis with crème fraîche—a stark contrast to the heavily adorned Japanese preparation. A practical note: North American sushi bars frequently confuse masago with the larger, crunchier tobiko from flying fish; the price difference usually reflects the genuine article.

Types & varieties

Natural Masago

Uncolored orange roe; most authentic and minimally processed option

Wasabi Masago

Green-colored with wasabi powder or artificial dye; spicy heat without wasabi burn

Spicy Masago

Red or orange-red, colored with paprika or chili; often includes chili extract for genuine heat

Black Masago

Colored with squid ink; used for visual contrast in decorative sushi rolls

Scandinavian Capelin Roe

Milder cure, sometimes brined rather than pasteurized; traditional Nordic preparation

Masago vs. Tobiko: Knowing the Difference

The two roes are often conflated on sushi bar menus, but they differ significantly in source, size, and sensory profile. Masago comes from capelin (a smelt relative) and measures 0.5–1.0 mm; tobiko comes from flying fish and measures 1.0–1.5 mm. On the palate, masago is softer and almost melts, while tobiko provides a more pronounced snap. Tobiko also carries a faintly smokier flavor. If a sushi roll lists 'masago' but the eggs have a distinct crunch and larger size, you're likely eating tobiko—common in establishments that use the names interchangeably.

Masago: smaller, softer, smoother finish; capelin source
Tobiko: larger, crunchier, smokier notes; flying fish source
Price typically reflects the distinction, with masago being the more economical choice

The Scandinavian Tradition

Outside Japanese cuisine, capelin roe occupies a distinct culinary niche in Nordic countries. There, the roe is often prepared with minimal intervention—a light cure or brine—and served on dark bread, blinis, or crackers with crème fraîche, chives, or dill. This preparation foregrounds the roe's delicate marine sweetness rather than masking it with colorants or heavy seasoning. If you encounter Scandinavian capelin roe, expect a milder, cleaner flavor profile and a texture that holds up better as a spreadable garnish than as a crunchy topping.

Tips & pitfalls

Apply masago from a squeeze bottle or small spoon for controlled, even distribution—no need to overwork it
If the roe appears dry, toss gently with a single drop of sesame oil or mirin to restore moisture and sheen
For sushi rolls, garnish with masago after cutting; the knife crushes and scatters eggs applied beforehand
Avoid high-heat cooking: masago is already cooked and turns rubbery if sautéed, pan-fried, or baked
Store the container upright in the refrigerator's coldest zone, not in the door where temperature fluctuates
When mixing masago into rice or mayonnaise-based sauces, fold it in just before serving to keep the eggs intact
Check ingredient labels for artificial dyes if natural coloring matters to you—many green and red varieties are synthetic
For a quick flavor boost, let wasabi masago steep with a splash of ponzu for 10 minutes before using
