What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Drain the prawns very well before seasoning so they sear in the masala instead of watering it down.
- 2Use a wide pan so the tomato-onion mixture reduces quickly into a proper thick thokku.
- 3Cook the tomatoes until oil shows at the edges; that is the cue the raw tang has mellowed.
- 4Add the prawns only after the masala is fully thick, because prawns cook in just a few minutes.
- 5Stop cooking as soon as the prawns turn opaque and curl lightly; tight curls usually mean overcooked.
- 6If the thokku gets too sour, balance it with a few extra spoonfuls of cooked onion-tomato masala rather than sugar.
- 7This dish tastes even better after a short rest, once the prawns absorb the tamarind-spice base.
Adapt it for your goals.
Extra-spicy
Increase red chili powder and add more slit green chilies for a fierier thokku that pairs especially well with plain rice.
coconut finishCoconut-finish
Stir in a little thick coconut milk at the end for a softer, richer South Indian style with less sharp tamarind bite.
dry thokkuDry-thokku
Use less water and cook uncovered at the end for a drier version that works well as a dosa or chapati side.
fish thokkuFish-thokku
Swap prawns for firm fish pieces and simmer gently; good if you want the same masala with a different seafood texture.

Tomato and Herb Goodness
Tomatoes, onions, green chili, and coriander leaves add plant compounds and freshness to the richly spiced masala.
