OK, I have been back to the guy and this is what he said:
He adds only 1 heaped cooks spoon of tomato paste to the base, I was amazed it was this little so double checked this twice but this is what he said. I asked if he added any other form of tomato and he said no, just this.
He adds a whole bunch of fresh coriander.
I asked if he uses chicken stock in the base and he said yes!, he says he adds it after the water, ie not the day after its made. I asked him if it was the stock or the jelly and he said not the jelly.
As I was leaving he said to tell him how I get on, I told him a few people have made this and one guy even plans to make the 30 onion full version and this tickled him ;D. His comment to us all was that we just need to keep practicing

YF - I will see how he makes a biryani next time I am there (I will have to order it to watch him cook it)
