I like this book.
It's not the most glamourous recipe book, nor the most accurate (be prepared to make a few attempts before achieving results that equal the photography).
There is little padding around the recipies. The author does manage to squeeze in short pieces regarding India's different culinary regions, but without sufficient detail to make them particularly informative. If you're looking for a read that goes further into ingredients, then try Ms Bharadwaj "India's Kitchen". Some of the recipies are indeed shared between the two books.
While this book isn't an all-encompassing bible, it does contain a nice range of dahl recipies. I've been looking for an Indian recipe book with a good selection of lentil and bean dishes, and this book neatly fits the bill.
Plenty of flavours, plenty of textures, just what I'd been looking for. Certainly a useful book for bean loving people, but useful also to those looking for veggie accompaniments to larger meals.
Jolly tasty stuff, just persevere with the recipies that don't come together on the first try.
