Interesting coincidence going on here. I came across the Gulshan article just after finishing my first attempt at the new Kris Dillon base and the only spice in that is 1 tsp turmeric and 1 tsp paprika (I used deggi mirch instead cos I didn't have any paprika) in nearly 3 litres of finished base. This base is basically just fried/boiled onions and tomato and by far the simplest I've done to date and to be honest I wasn't expecting too much of it, well we had madras on Friday, bhuna last night and I've just made another bhuna for tonite, so I suppose you can say it works for us! The base seems to cook very well when making the finshed dish and if you want to tweak it with extra spices then why not, I think next time I'll throw in some whole spices and remove them before blending, definitely worth a try.
