Once being a basic food of farmers and poor families in Vietnam, com tam or broken rice is now a favourite dish of most Vietnamese. It is said that the best broken rice can be found in Saigon. When you come to Saigon, you should try this dish at least one time and you will not regret it.

Com tam literally means broken rice. Broken rice originally consisted of grains which were broken during the harvesting and cleaning of rice.

Local broken rice eateries can practically be found on every street in Saigon. A broken rice dish is served with many beautiful colours from grilled pork chop with multi-flavour to steamed egg, shredded pork skin, pickles, vegetables such as tomatoes, cucumbers ... and especially sweet fish sauce that is the spirit of the dish.
