It's a green pepper, looks like a jalapeno, pretty meaty for such a small pepper, and the bite on that thing will have you taking little mousey nibbles from it, even if you can handle ghost pepper hot sauce with no problem at all points at self. It has a really unique flavor too, one that I've never tasted in any other pepper (kinda floral). Either Namaste has got the best jalapenos I've ever had (although how hot it is leads me to believe it is not a jalapeno), or this is a different kind of pepper and I would really love to know what it is and where I can get it. Whenever I order biryani from there, it always comes with half of one of these peppers on top.
