I'd have to agree and it takes me back to my initial mental dilemma with BIR mixed powders. However, nearly all are based on using a 'curry powder' and other spices to make a different 'mixed powder'. I simply had to accept it and move forward. I always asked why you couldn't simply make it from scratch and of course, you could. Most don't and so to get the same result we do the same. If you wanted to make a powder that uses a 'curry powder' from individual spices, you'd need to know the ratio of spices in the brand curry powder. They don't give that out.
Of course I'm not getting the same thing anyway because I don't have access to Rajah. Whether this is significant is unknown.
Korma/Madras/Vindaloo as chilli heat indicators?
My daughter's friends recently moved and sampled the local Indian which has dishes in 5 heat levels. Mild, regular, hot, super hot and blistering. They tried all mild the first time and felt they could go hotter. Second time they bought just 1 regular dish and couldn't eat it. Nothing spoils a curry for someone more than too much chilli heat.
