Ilish Bhapa (ইলিশ ভাপা)

A Bengali Comfort Classic

Chef’s Tips

• Soak mustard seeds before grinding for a smoother paste

• Use ice cubes or cold water to keep the paste cool while grinding
• Do not strain the mustard paste if using a good mixer
• Rest the fish for 5 minutes after steaming before serving

Frequently Asked Questions

• Why does mustard taste bitter? Usually due to over-grinding, overheating during grinding or old mustard seeds
• Why soak the mustard? Soaking softens the seeds so they grind faster and more smoothly
• Why add coconut? Coconut balances the sharpness of mustard and gives the gravy a richer texture
• How do I know the fish is cooked? It should be opaque, flake easily and separate cleanly from the bone
• Why is my gravy watery? Too much water while grinding, a loose lid during steaming or condensation entering the container can thin the gravy
