Pla ra

Pla ra (Thai: ปลาร้า, pronounced; Northeastern Thai: ปลาแดก, pronounced), similar to padaek in Laos, is a traditional Thai seasoning produced by fermenting fish with rice bran or roasted rice flour and salt in a closed container for at least six months. Fermented fish seasoning is commonly found in Cambodian, Lao, Mon, Thai, and Vietnamese cuisine. 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.
