This is Naved’s special dish at Dishoom Covent Garden. It’s a light, fragrant and utterly delicious south-Indian-style curry, packed with juicy prawns and tempered with coconut milk. Although it looks impressive, it is actually very easy to make, so you can serve it either as a week-night supper or as an indulgent dinner. We serve it with idiyappam, the white, lacy noodle pancakes, also known as stringhoppers. If you can’t get these, it goes just as well with steamed rice.
