What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Roast the whole spices only until aromatic; over-darkening will make the kuzhambu bitter.
- 2Cook the onion-tomato base until the tomatoes turn jammy, or the gravy can taste sharp and underdeveloped.
- 3After adding the ground masala, wait for oil to show at the edges before pouring in tamarind extract.
- 4Add fish only once the gravy has simmered and slightly thickened, so the pieces do not break apart.
- 5Swirl the kadai instead of stirring after the fish goes in to keep steaks or fillets intact.
- 6Resting the curry for at least 10 minutes deepens the tamarind-spice balance and improves the texture.
- 7This kuzhambu often tastes even better the next day; reheat very gently so the fish stays tender.
