Ive used sriracha in bir , I used to get a curry called Nepalese from a TA near me , also in the northwest, I could see the chef cooking it and i asked what the sauce was , he told me sriracha,he also told me to get it from the chinese shops as it is from thailand. I tried to replicate the Nepalese curry by making a jalfrezi and adding sriracha and lemon juice very nice indeed . I also have it on chicken tikka nan with yogurt.
