Thailand is a country that produces some excellent cuisine. They have a masterful knowledge of how to combine sweet, sour and saltiness with piquancy of the Chilli, to provide an explosion of flavour. This dish is a great starter for a Thai theme meal evening or simply as a comforting pick me up on a cold winters night. To make the dish more substantial, simply add pieces of cooked chicken, which will readily absorb the wonderfully flavoured broth.
