A. Sriracha is a fiery chilli sauce introduced by David Tran, a Vietnamese refugee who came to the United States. But the origin of the sriracha dates way back to Thailand. A woman named Thanom Chakkapak invented the recipe for the famous Sriracha sauce in Thailand. She began by sharing the sauce with her friends and family before producing it on a larger scale. Moreover, the traditional version has a sweeter taste than other varieties.
