Grilled Ilish with Gondhoraj Lebu and Mustard Sauce | Taste Matters

“Bangla aamar sorshe ilish, chingri kochi lau || My Bengal lives in mustard Hilsa, prawn with tender pumpkin

Bangla parshe maachh ke dhuye jeerer bataye dau || My Bengal lives in Parshe fish curry with cumin paste.”

Noted lyricist Giasuddin Dalal has beautifully described the importance of fish in a Bengali kitchen in the above quoted Bengali song. Going one step further, he has also shown the way how Hilsa marries with mustard paste in the culinary world. The queen of fish “Hilsa” popularly known as “Ilish Maach” is the essential ingredient of Bengali Cuisine. Not just Bengalis, anyone fond of fish, obsesses over Ilish.

It has become a ritual to pair up Ilish (Hilsa) with mustard in my kitchen when  Monsoon arrives. The combination of mustard seed’s paste, mustard oil, green chili and onion seeds give a unique distinct flavor to this fish.

Gondhoraj Lebu is an aromatic citrus fruit native to tropical Asia including India, Nepal, Bangladesh etc. Call it nemu, lemon, lime or lebu; a few drops of Gondhoraj Lebu juice creates a magic by releasing an intense citrus fragrance. A fusion of traditional mustard Hilsa and Gondhoraj lemon juice brings the different flavors together to create a culinary magic. However, one should keep in mind as not to temper with too many ingredients as this fish has got its own unique flavor which must be retained.
