It was last september when madhurjaffrey began her cookery course on bbc two. nearly 2 million people have watched spellbound as she unravels the mysteries of indian cuisine. there were letters. there were people calling in, people getting so excited. as i came in at immigration, they would say, well, so what are you making today? to be able to do it yourself and have something tasty that nobody s ever served to you before was quite something in people s homes. whatever i was making that particular evening would be cooked by everybody all over england. the day after i cooked a chicken with green coriander, they ran out of green coriander in manchester. this, i was told. so they were reactions like that, that whole city the following day, everybody s cooking, that particular thing.
