It is a type of sauce in Thailand with somewhat complex origin. The sauce was created and is popular locally in Sriracha for long (originally known as Nam Prik Sriracha) but the sauce was popularize across the country by Sriraja Panich, who is the first to produce the sauce commercially as Sriraja Sauce. Sriraja Panich couldn't trademark the brand due to law in Thailand disallowing region name to be used as a trademark. This fact spawn several brand using the name Sriracha sauce and caused the name Sriracha sauce to become a type of a sauce here in Thailand. Sriracha city even put the "town of delicious sauce" as their official motto. Many Thais still consider Sriraja Panich as the only genuine Sriracha sauce maker (even though they're now own by Thai Theparos), and do not have a good impression of the US-made Sriracha sauce brand.
