What is "Sriracha" used in Bloody Marys

Sounds like you have an urgent need for it now, but when you have time, it's even more addictive when you make your own (and surprisingly easy to do): http://www.food52.com/recipes/6441_fresh_sriracha_aka_home_made_rooster.

It is chili based and if you don't have it in your regular grocery store in the Asian food aisle try an Asian grocer. It is addictive!!

It is a hot sauce, like Tobasco, only better and thicker.
