Neil Perry's sour and spicy prawn soup with noodles William MeppemThis is a delicious tom yum-style Thai soup with noodles,which can be served several ways. You can,if you like,strain the bits and pieces out of the broth,but the more authentic way of serving it is to leave them in. And you could replace the prawns with shredded chicken. As a matter of fact,barbecue pork (from your local Chinatown) would taste pretty damn good in this soup,too.
