I've tried it and found it not to be very hot. I like the stuff with the rooster on the big red squeeze bottle. It's called Sriracha. Here's a link to mohotta.com

I've used this stuff for years to cook with. My mashed potatoes and potato salad turn out slightly pink cause I use it in place of black pepper. It has a wonderful flavor!
Wonderful flavour, and just as hot as you want it to be.
