Steps
Cook the onion · About 7 min

Check: The tomato is soft and the sauce coats a spoon.
Cook the prawns · About 5 min
- Add 600 g peeled raw prawns, deveined. Stir gently over medium-low heat for 3–5 minutes.

Tips
- Cook the sauce before adding prawns.
- Overcooked prawns curl tightly and become rubbery.
Substitutions
- Use frozen raw prawns, thawed in the fridge.
- Use canned chopped tomatoes instead of fresh tomatoes.
Storage
- Refrigerate perishable food within two hours, or within one hour in heat above 32°C / 90°F. Store covered at 4°C / 40°F or below. Use within two days for this draft.
- Reheat cooked dishes to 74°C / 165°F, stirring or turning for even heating. Serve cold salads, dips and chilled desserts directly from safe refrigeration.
- For sauces and soups, add a little water if thick and reheat gently. Crisp coatings soften after storage.
Make ahead
- Make the masala one day ahead and chill.
- Reheat the sauce before adding uncooked prawns.
FAQ
Can I use cooked prawns?
Add them only at the end and heat to 74°C / 165°F as reheated leftovers.
Why are the prawns rubbery?
They were likely cooked too long. Stop once opaque and firm.
Can I leave the tails on?
Yes, but tell diners so they can remove them.
