Sriraja Panich was created in Thailand in the 1930s by home cook Thanom Chakkapak and her family. They named the sauce after Chakkapak’s hometown of Si Racha.
Huy Fong is on top of the hot sauce world but residents of Si Racha generally feel that its sauce lacks the subtlety of hometown favorite Sriraja Panich.
Huy Fong sriracha is a thicker sauce that brings heat to a dish, while the thinner Sriraja Panich is known for its subtle blend of hot, sweet, and sour notes.
For many people, sriracha is synonymous with Huy Fong's spicy sauce but authorities like the U.S. Patent and Trademark Office consider sriracha a generic term.
Think of a Huy Fong sriracha ad. If you can't, there's a reason: Huy Fong doesn't advertise, has a shockingly simple no-frills website, and has no social media presence.
