The sauce's recipe has not changed significantly since 1983.[citation needed] The bottle lists the ingredients: "chili, sugar, salt, garlic, distilled vinegar, potassium sorbate, sodium bisulfite and xanthan gum". Huy Fong Foods' chili sauces are made from fresh, red, jalapeño chili peppers and contain no added water or artificial colors.[9] Garlic powder is used rather than fresh garlic.[10] The company formerly used serrano chilis, but found them difficult to harvest. To keep the sauce hot, the company produces only up to a monthly pre-sold quota in order to use only peppers from known sources.[3] The sauce is certified as kosher by the Rabbinical Council of California.[11]
