The most famous Vietnamese-restaurant condiment in North America was not invented in Vietnam. This episode follows sriracha from a Thai coastal town with Chinese immigrant roots to a pop culture flavor and a supply chain crisis.

We cover the Si Racha district, Cantonese culinary influences, the 1932 gold medal won by a local cook who could not trademark the district’s name, and the brands that carried Thai sriracha abroad. We then compare the runny Thai dipping sauce with Huy Fong’s thick jalapeño-based rooster sauce, its adoption by fast food chains, and the 2022 shortage after its split with Underwood Ranches.
