Pla ra

Pla-ra (Thai: ปลาร้า [plaː ráː], Lao: ປາແດກ [paː dɛːk]) is a traditional Thai seasoning produced by fermenting fish with rice bran or roasted rice powder and salt fermented in a closed container for at least six months. Pla ra is mostly used in northeastern food such as green papaya salad. Pla ra has a very strong smell, which is considered unpleasant by some people. Its flavors are salty and sour, depending on the amount of salt put in and lactic acid resulting from fermentation process.
