Steps
Cook the onion · About 7 min
- Heat 25 ml neutral oil. Cook 180 g onion, chopped for 6–7 minutes; add 15 g ginger-garlic paste for 1 minute.
Reduce the sauce · About 10 min
- Add 250 g tomatoes, chopped, 1 tsp ground coriander, ½ tsp ground cumin, ½ tsp chili powder, ¼ tsp turmeric, ¾ tsp salt and 80 ml water. Simmer for 8–10 minutes.
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.
Check: The prawns become opaque and firm; check 63°C / 145°F where a probe fits.
Finish · About 1 min
- Stir in ½ tsp garam masala, 15 g coriander leaves; serve immediately.
Tips
- Cook the sauce before adding prawns.
- Overcooked prawns curl tightly and become rubbery.
Substitutions
- Use frozen raw prawns, thawed in the fridge.
- In Prawn masala, replace fresh tomatoes with canned chopped tomatoes.
Storage
- Get perishable Prawn masala into the fridge within two hours, or within one hour above 32°C / 90°F. Eat Prawn masala within two days, keeping it covered at 4°C / 40°F or colder.
- Bring cooked Prawn masala to 74°C / 165°F, stirring or turning it for even heating. When Prawn masala is part of the meal, serve cold salads, dips and chilled desserts straight from safe refrigeration.
- If Prawn masala includes a thick sauce or soup, loosen it with a little water during gentle reheating. Any crisp coating on Prawn masala becomes softer in storage.
Make ahead
- Make the masala one day ahead and chill.
- Reheat the sauce before adding uncooked prawns.
