Ikura, or salmon roe, is one of Hokkaido’s most prized seafood delicacies. Each bright, jewel-like egg gently pops in the mouth, releasing a rich umami flavor that makes it a particularly popular sushi topping in Japan.
In Japan, the word ikura usually refers specifically to salmon roe. Interestingly, the word itself comes from the Russian language, where “ikra” means fish roe in general.
Fresh salmon eggs are initially contained inside the female salmon’s ovaries. In this form, they are called sujiko. Sujiko consists of immature salmon eggs that remain attached to the ovarian membrane and are commonly preserved whole with salt.
To make ikura, the individual eggs are carefully separated from the ovarian membrane and are usually seasoned with soy sauce. The degree of maturity is particularly important. If the eggs are too immature, the delicate membranes can easily break apart. If they are too mature, the outer membrane becomes tougher and can leave an unpleasant texture when eaten.
For this reason, salmon roe is harvested and selected at just the right stage of maturity, when the eggs have developed the ideal balance of firmness, texture, and flavor.
The finest ikura is traditionally associated with the eggs of chum salmon that have matured as the fish return from the sea to Hokkaido’s rivers to spawn in autumn.
September and October are therefore an especially important season for enjoying fresh Hokkaido ikura. Served over warm rice, as sushi, or alongside other seafood, its distinctive texture and concentrated umami provide a quintessential taste of Hokkaido’s autumn waters.
