Pro Tips
- →
Add the prawns near the end and cook them briefly — they toughen and turn rubbery very quickly if left in the simmering curry too long.
- →
Let the curry base develop flavor for several minutes before adding the prawns, since they need very little cooking time themselves.
- →
Use fresh curry leaves if possible for the most vibrant, authentic aroma.
Variations
- •
Add a green chili slit lengthwise for extra heat.
- •
Some households use crab or squid instead of prawns using the same technique.
- •
Serve with string hoppers instead of rice for a different traditional pairing.
Storage
Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of water or stock to loosen the texture.

Frequently Asked Questions
Why are my prawns rubbery?
They were overcooked — prawns need only 3 to 4 minutes in a simmering sauce, since they cook very quickly and toughen fast past that point.
Can I make the sauce ahead?
Yes, the curry base can be made ahead and reheated; add fresh prawns only at the very end when reheating to serve.
What if I can't find tamarind paste?
A mix of lime juice and a touch of brown sugar can approximate the sour-sweet balance, though the specific tamarind flavor won't be replicated.
