This recipe comes from Jacki Passmore's All Asian Cookbook, published in 1978. The curry is hot, as it should be, but has amazing depths of flavour. I've tried ready made pastes and numerous Indian restaurant offerings and nothing comes close to it, although my sons recently holidayed in Fiji and discovered a similar version in an Indian restaurant - one son told me that he had found the second best Vindaloo. Must have been good - they went to that restaurant 2 nights in a row, and they only had 4 nights there.
I use a coffee grinder to grind the spices.
From Indian Regional Classics by Julie Sahni.
This is the most aromatic and fragrant of all Indian spice blends. Used throughout North India in all types of dishes — from appetizers and soups to yogurt salad and main courses — this blend is indispensable to Moghul and North Indian cooking. It is widely available, but the homemade version is more fragrant and, of course, fresher.
This recipe is a lot of work, but is definitely worth it. Chopping everything in advance makes it go smoother. Ghee is butter that has been slowly melted so that the milk solids and golden liquid have been separated. Vegetable oil can be used but ghee gives a more authentic taste
