I did both - but. I didn't have coconut milk so subbed regular milk, and the grocery store only had low fat yoghurt, and finally i was out of tomato paste so used a diced fresh tomato with a bit of anchovy paste. So I will probably remake the dish with all of the specified ingredients. It was okay, at least it was recognizably curry, but the flavours were not complex or deep - not blaming the recipe, as I deviated from it.

I've also bought me a well-recommended indian cookbook but it appears I have to read through the history of India before there's any cooking.
