Asma Khan’s new cookbook, Ammu, is named after her mother – and it’s full of recipes from different family members.

This one is from Khan’s childhood nursemaid, who she called Ma. Described as a “formidable person”, Khan says Ma always made this dish for her when she returned home to India from England.

“It’s a simple, heart-warming, no-fuss dish that only takes 45 minutes or so to make. I eat Ma’s prawns with plain boiled rice.”

Reduce the heat, cover and simmer for 15 minutes.
