Chef's Authentic Tips
- Always grind mustard seeds with a pinch of salt and a green chilli; this chemically prevents the enzyme myrosinase from turning bitter.
- A final drizzle of raw cold-pressed mustard oil right at the end (Kancha Tel) is the soul of authentic Bengali cooking.
Smart Substitutions
- If Hilsa is unavailable, salmon or trout with their natural high fat content make the closest substitute.
Serving Suggestions & Pairings
- ✓ Serve steaming hot with hot basmati rice; drizzle the golden mustard sauce over the rice and savor each bite.
