Fish roe, the mature eggs of fish, are a delicacy in many cuisines around the world. With a distinctly sweet, briny flavor and a satisfying pop when bitten, they make an interesting addition to many dishes. Specific types include salmon roe, which is large and orange, and tobiko (flying fish roe), which is smaller and often brightly colored.
Regarded for its high protein content, fish roe also boasts a rich store of Omega-3 fatty acids, vitamins, and minerals. Enhancement of nutritive value aside, its inclusion can amplify the visual appeal of a dish with its jewel-like veneer. It's often used in sushi, but is also delicious atop crackers or in pasta sauces.
