Wow, thanks for all these replies!
I suppose I had this (possibly completely erroneous) idea that 'modern' Indian cooking was a lot lighter and fresher than some traditional dishes. Maybe not the case, and many apologies to anyone actually from India for my total ignorance!
All I know is that I like eating Indian food and given that I'm blessed with living in a very multicultural area with lots of Indian shops, I quite fancy learning how to make stuff.
