Having launched this project with our own two grandmothers, Rajni was our first ‘unknown’ and thus most nerve-wracking. We didn’t yet have our ‘routine’ nailed, and we’d driven all the way to an unknown street in Leicester, trusting her granddaughter Ria’s insistence that Rajni was a culinary legend. Ria was not biased; the nerves evaporated and it was one of our favourite days. We went straight into the kitchen, already full of flavour, and watched her casually make three curries, lassis and dessert in a sort of narrated performance, wearing a beautiful turmeric-coloured sari.
