Hi Mike.
Yes Baltis do have their own bases. Generally they use a fair few whole spices and a special GM too. I originally used the Kushi Base from this website and have had reasonable success with it. The recipe from the subscription website is a completely different animal. It contains a lot of full fat milk and frozen cauliflower!!
I didnt have any frozen cauli so I used fresh. The finished gravy had a different smell about it, and to be honest, I doubted the potential of it. As far as the way I cooked the curry, I didnt do anything different to how I would usually cook one ie G&G, Tom puree, Spices in (martinvics balti GM), ladle of gravy, oil separation, 1/2 tsp pomegranate seeds, ladle 2 of gravy, reduction & oil separation, 3rd ladle gravy, final reduction & serve
Not sure about copyright infringements etc so dont think I could post the recipe in the public domain.
Cheers
Mick
