This is my adaptation of a mango and chilli icecream, which I ordered in a restaurant years ago. I use the small birdseye chilli. The sweetness of the mango is the first thing you taste, and as you swallow you get the warmth of the chilli in the back of your throat. The coldness of the sorbet blunts the heat of the chilli, so you need more chilli than you would think. I have never seen any version of this recipe written anywhere, so I thought it was time I posted it.
