Hilsa or firm fish fillet
Book already gives grams; fish fillet weight varies, so no piece weight.
Instead of Hilsa or firm fish fillet
No vegetarian swap tastes like hilsa; paneer or raw jackfruit are texture compromises only.
Kingfish or mackerel filletUse the same weight. Mackerel comes closest to hilsa's oily richness; simmer 2–3 minutes less so it does not break up.
Firm white fish filletUse the same weight. It is leaner and milder, so the curry will taste less rich; add it later and cook gently for 5–7 minutes.
PomfretUse the same weight. It is delicate and sweet; keep the simmer gentle and shorten cooking by a few minutes.
Vegetarian swaps
PaneerUse the same weight, cut into cubes. Add 8–10 minutes before the end; do not simmer hard or it turns rubbery.
PotatoUse about 125% of the fish weight, cut into chunks and parboil until just tender. Add 15 minutes before the end; it thickens the gravy.
Raw jackfruitUse the same weight, parboiled for 15 minutes and cut into pieces. Simmer for 15–20 minutes; it gives a meaty texture but a milder taste.
