A fixture at Vietnamese restaurants, Sriracha sauce can lace aromatic pho with a jolt of heat. It's the star ingredient in spicy mayonnaise zigzagging countless sushi rolls, and it has even inspired a legion of fans to dress up for Halloween each year like a red plastic squeeze bottle with a green cap.
But this year, a shortage of red jalapeño chiles has threatened it all for Sriracha, a beloved condiment made from sun-ripened peppers from Mexico and seasoned with vinegar, salt, sugar and garlic.
Huy Fong Foods, a company based in Irwindale, California, that produces one of the most popular Sriracha sauces in the world, confirmed that it was experiencing an "unprecedented shortage" affecting all of its chile-based products, which also include chile garlic sauce and sambal oelek.
In a statement by email, a company representative said that the issue stemmed from "several spiraling events, including unexpected crop failure from the spring chile harvest." Huy Fong Foods generally goes through 100 million pounds of chiles each year, the representative added.
The company had foreshadowed the Sriracha scarcity in an April letter to customers announcing that unfavorable weather conditions had resulted in a "severe shortage" of chiles. It said that all orders placed after mid-April would be paused until September.
"Unfortunately, this is out of our control and without this essential ingredient we are unable to produce any of our products," the company wrote.
A persistent drought this year in Mexico hindered irrigation and caused "spectacularly low yields" of the red chiles, which are grown primarily in four northern states of the country during the first four months of the year, said Guillermo Murray-Tortarolo, who researches climate studies at the National Autonomous University of Mexico.
Climate change is a possible factor causing the drought, Murray-Tortarolo said, adding that the drought was most likely to intensify and cause future production supply issues and cost increases for customers.
