Nona Ilish Keeps Bengal’s Salted Hilsa Tradition Alive
Nona ilish is a special way of preserving hilsa fish with lots of coarse salt.
The fish is cut, salted inside, and left to dry for several weeks.
This tradition began around Chandpur in Bangladesh, where many hilsa are caught.
The preserved fish was useful when it had to travel long distances.
It later became known in Kolkata and other parts of West Bengal.
People usually soak it for many hours before cooking to remove some salt.
It can be made into mashed dishes, fritters, curries or leaf-wrapped preparations.
Many Bengali families associate it with grandparents and older family kitchens.
Although its strong smell and taste are not for everyone, devotees consider it a treasured delicacy.
Nona ilish is hilsa scaled, gutted, heavily salted and dried for four to six weeks.
The preservation method is associated with Chandpur in Bangladesh and later spread to West Bengal.
Small 300- to 400-gram hilsa, called khoka ilish, are commonly used.
Preparation can require hours or an overnight soak because the fish is intensely salty.
The dish remains rare but cherished for its distinctive taste and family memories.
