I do love a good Kashmiri Korma, and many other northern dishes. Whilst I do love the flavours in southern Indian / Sri Lankan cooking, it tends to be a bit on the hot side for me!
As per a previous poster, I'll caveat that with this is based on the Indian cooking we get in the UK, which I'm sure is somewhat removed from its original inspiration.
If you like curries, come to GLA, where it's a bit of an obsession. There's a curry house on almost every corner, and usually of a good standard. There are also a good number of modern Indian restaurants, which offer something different to 'standard' fare. All of which has contributed to GLA winning "Curry capital of the UK" several times recently, ahead of stiff competition from the likes of Birmingham (home of the Balti) and Bradford (home of lots of traditional cooking).
