When I made Chewys Madras i used a tsp of regular chilli powder cos the Kashmiri chilli p in my local spice shop would blow your head off!! a half tsp would equal a tsp of regular stuff! ,
I have to agree with there being a lack of decent Curry houses I live in Dublin and there used to be some VERY good ones and now best ones are the upmarket ones where it costs an arm n a leg for a meal for 2, there's a few very decent ones but it's hit n miss so much so i can remember specific curries going back 3 years or so especially when i'd encounter an absolute belter which is about once a year
