Hi Adey,thanks for the recipe and the contributions to the forum,hope they continue.Looks a very complex massla sauce,although to me that's not a bad thing.I'm always disappointed when a massla sauce recipe is just your usual Patak's paste combined with yogurt and food colouring.It reminded me of the recipe from the Little India Restaurant that was posted by CBM.I'm sure that had some tinned fruit or something similar and proved to be a bit controversial at the time.
A couple of questions if I may.Definitely no tandoori or tikka paste in the recipe? You say add to pan with korma ingredients(from your book) but the korma recipe already has raisins/sultanas as well as ghee and g/g paste...so are you saying add more??
mushroom Mike, jb, recipe was shown to me by my chef plus a few others, with a few slight changes.
With so many BIR eateries popping up on top of what we already have, my chef made a valid point, that to survive, you need to be better than your competitors! How true, i.E we have hundreds of Mcdonalds, but you know, any 1 you go to , you get the same thing! Not so true with BIR. After using this recipe since we opened in 2012, we sell more and more each week, with rave reviews

As regards the tikka/ tandoori paste, NO! Its already in the marinade, too much will kill the dish.
And yes, add more as i stated, you are using the korma sauce as a foundation for the massala sauce

Hope this helps, and remember, this is just MY personal approach, based on Sales and customer feedback, so please feel free to try the other recipes on the site.
Regards, A
