I wonder why this idea took so long to come to fruition. Huy Fong Foods, Inc. now sells Sriracha packets in 50 and 200-pack options. If you're familiar with standard ketchup packets you'll be right at home with these.
The packets are perfect for stashing Sriracha while on the move and can be yours for $14.99 (50 packets) or $34.99 (200 packets). Get them here.
