"Shirako" is a Japanese term referring primarily to the white reproductive organ (milt) found in the belly of male fish. The mature shirako of fish like cod, anglerfish, and pufferfish is known for its delicious taste and is frequently used in various dishes, such as raw salads, soups, hot pots, and grilled dishes. The reproductive organ (eggs) of female fish is called "goni". In sushi restaurants, grilled pufferfish milt is especially popular for its creamy and exquisite flavor.
