Do they simply use chilli power? Or do they use fresh chillis and/or some kind of pre-mixed chilli paste?
Well Cory,
This is an interesting one!
I knew a chef who used a mixture of fresh chopped chillies and also chilli powder.
He swore to me that he only used ordinairy chilli powder
Never use the the "extra hot"
He claimed that it tasted too powdery
I believed him, but a couple of months later, I saw that he had a bag of it in the kitchen!!
Normally the chef doesn't buy what he cooks with
He is at the mercy of the restaurant owner, and he will most likely decide things by their price
