The enormous city of Chongqing (once part of Sichuan but now a province in its own right) is renowned across China for having some of the most ferociously hot and spicy food in the whole country! This favourite local dish (known as xiao mian) is made with a rich and aromatic chilli oil flavoured with lots of fragrant Sichuan pepper and dried chillies. It's often served with cooked yellow peas on top - here, chickpeas are a very good substitute.
