What is Masago?
Masago, also known as capelin roe, is the egg of the capelin fish, a small species belonging to the smelt family. This bright orange-colored roe is a common sight in Japanese cuisine, frequently used as a colorful and crunchy garnish on sushi rolls, rice bowls, and salads. While its primary appeal is its texture and flavor, masago is also valued for its impressive nutritional profile relative to its small serving size. It is important to note that masago is often dyed to achieve its vibrant orange hue.
