Excellent looking bird and meal! I bet it was mighty tasty.
I was under the impression that Piri Piri is cooking using the African bird's eye chili?
I was able to find a rub from "Pepper Pilot" a website, and forum member on another forum, that packages his Peri Peri with the African bird's eye chili. It is about half as hot as a habanero - around 175,000 scoville.
It has a beautiful flavor - spicy/hot enough to catch your attention and leave you craving for more - but not quite hot enough to "stop you in your tracks, hot". It's lovely, and highly recommended, if you can get a hold of some.
Yes you are 100% right but i run out of bird's eye and i had only Cayenne Chili Peppers in my garden
