Sriracha sauce is available in 17 oz bottles (perfect for your purse or briefcase) and 28 oz bottles (for the kitchen table), but at the request of so many loyal customers, Huy Fong will begin offering 1-gallon bottles for restaurant use (and for the most hardcore of addicts.) To-go packets are also available in some locations, great for traveling and hot-sauce emergencies.
You can find Sriracha sauce in almost any major supermarket, Asian market, and many restaurants.
