Until I (very recently) joined this site, all I knew about BIR was what I'd read in KD's The Curry Secret and The New Curry Secret. I live in Berlin, Germany, and believe you me, BIR is (or can be) wonderful - (I'm a British immigrant/expat here) - German Indian Restaurants, with a few honourable and notable exceptions are generally, well.....ermmm.....think of an anagram of "carp" :-)
So, anyway, I experimented a couple of times with the KD2 base and made a few dishes from the New Curry Secret with which I was delighted - aha!, this is close to BIR, the closest I've got so far, at least - and accompanied them with her Peshwari Pilau - best rice dish I've ever made - sweet and fragrant. I'll certainly make it again.
Reading about bases here, I think I want to make the next one slightly sweeter and the idea of adding a red or green pepper appeals to me for that reason. Cabbage and/or carrot and/or potato? Maybe.
However, my question is mainly about approaches to bases. In the New Curry Secret, KD makes the point that KD2 smells good even while you're making it, and I must admit that I like the smell of frying onions.
OK experts - (1) any discernible differences between frying/boiling when it comes to bases? (2) What difference(s) do the omission or addition of potatoes, cabbage and carrots make?
Many thanks in advance.
(PS - had a brief email exchange with KD - she's really friendly and cares about producing quality, tasty food - bless 'er!)
