I made CT's chicken rogon josh again this week, the first one as per the recipe and the second without chilli of any kind (for a chilli intolerant individual). I replaced the chilli powder with a tsp of paprika and just omitted the chilli and coriander paste. It was still a very nice (but mild) rogon josh.
