The photo for this recipe's got me going - that looks beautiful UB!

The amount of chillies in there is madness though isnt it?
I like chillies and have quite a high threshold but i cooked a madras yesterday with 3 green chillies split lengthways and a tsp of kashmiri (weak) chilli powder and it was pretty freekin hot!
Do you use indian chillies? I cant find out the name of the species but the ones most BIRs use that are only a bit longer than birds eye chillies.
I've been using them recently as my nearest shop is a bangladeshi veg shop and they cost practically nothing. 26p for a big handful! Very hot though!
