OK this ones for yellowfingers, I finally got back to my friendly takeaway and ordered the above.
He used 2 pans to cook this one for the sauce, the other for the rice.
The madras sauce was very basic, get 1 cooks spoon of oil very hot then add a TBSP of tomato paste (the more I look at this the more I think it might actually have ketchup mixed in it or even be ketchup), 1 TSP of res. masala, 1 TSP chilli powder and a squirt of lemon juice, fry this lot for about 20 seconds then add a small amount base, evaporate this and then add a ladle of base, simmer for 5 mins. This sauce turned out very smooth indeed and had the taste. I didnt notice him adding salt which is unusual and probably means he doesnt MSG unless it is in the base.
For the biryani he used 2 cooks spoons of oil not 1, he started with a TBSP of pre cooked onions and the chicken tikka, fry this lot for a few mins and then add fresh coriander and fry for a few minutes more, while this is going on he microwaved precooked pilau rice. He added a load of this to the pan and stir fryed for a few minutes more.
He added in a chopped raw tomato and wedge of lemon to the rice in the container.
