What Is Masago Sauce? Taste, Recipe, Nutrition

Do you like sushi? Then chances are you have heard about masago, an egg of the capelin fish, which is a type of foraging fish found in the North Atlantic, North Pacific, and Arctic oceans. Masago roe is only 1 millimeter wide, which is a lot smaller than other types of fish roe, including tobiko. One capelin fish produces around 56,000 eggs per season. Masago is yellow in color, but it is often dyed in a bright orange color, which is more appealing. Masago roe can also be dyed black, green, red, etc.

Masago is often used to top salads and sushi, but it can also be added to sauces. In this article, we will learn what masago sauce is, what it tastes like and how to make it at home since masago sauce is not yet produced commercially.

The main ingredient in the masago sauce is masago roe, which is an egg of the capelin fish.
