Dunlop writes from first-hand experience, with a finely sharpened cleaver in hand as it were, and her own journey has been no less engrossing. Her trial by Sichuan pepper began in 1994 when she landed up at Chengdu&rsquos Sichuan University on a British Council scholarship to study Chinese. The move was, in part, guided by her interest in the food, which had been piqued by a few previous visits. She eventually signed up for private classes at the Sichuan Institute of Higher Cuisine. After she finished her course at Sichuan University, the principal of the cooking school invited her to enrol as a regular student. This was a rare honour, since no foreigner had done it before. Thus began three months of intense training, including educational stints at local restaurants. Over the decades, Dunlop&rsquos knowledge of Sichuanese food has widened. So, when it was time to revise the book, she took up the challenge gamely. (&ldquoWriting a cookbook that attempts to encapsulate the cuisine of a place is like pitching a tent on quicksand.&rdquo)
