About this recipe

Sorshe Ilish is one of Bengal's most celebrated fish curries where the flavour of hilsa shines through a light but intensely aromatic mustard gravy. The secret lies in grinding mustard correctly, balancing it with posto, lightly frying the fish and cooking it gently without boiling the gravy.

Frequently asked questions

Why use both white and black mustard?

White mustard provides body while black mustard adds sharp flavour

Why add poppy seeds?

Posto softens the pungency of mustard and creates a creamier gravy

Why use ice cubes while grinding?

They keep the mustard cool and reduce bitterness

Why fry the fish first?

Light frying helps the fish retain its shape during cooking

Why should the gravy not boil vigorously?

Excessive boiling can make the mustard bitter and overcook the hilsa
