I’ll start with something as simple and unassuming as rice. When I try to think of all the uses for this grain I immediately go dizzy with the countless possibilities – within and between cultures, pairing with other ingredients, all the types of rice available, the methods of cooking and when you serve it, the consistency, degree of processing, home cooking, commercial uses. I think of paella, wild rice salad and ho fan noodles. I visualize arancini with their golden breadcrumb crust, Iranian saffron rice with potatoes, Chinese fried rice, rice pudding. I recall plain steamed rice my mum used to prepare for me when I had a bad tummy, with only a little bit of butter stirred in at the end.
