OK this weekend after Pete's success I tried the following:
Made the KD base with the following changes:
Added half a green pepper and half a small carrot to stage 1
Added 400ml of oil to stage 2
Added 1 TSP MSG and a chicken stock cube at stage 3
I then skimmed off almost all the oil to cook with.
I then tried a gurkha masala, pre fried onions, peppers and lamb mince all with skimmed oil
Tried darths boiled chicken method which worked fine but I think I prefer bruce edwards pre cook chicken.
For the final curry (for 2), loads of oil from the gravy (I recycled uneaten oil at the end), browned the ginger and garlic puree (used nishan)
Then added pre fried onions, peppers and lamb, added a TBSP of 100 baltis balti spice mix, quarter TSP of hot chilli powder and TSP of salt, added 2 TSP of tomato puree and ketchup mix, pinch of methi
Added chicken and then a ladle of base, evaporated and then bit more base, reduced the whole lot down (KD base is very watery)
Unfortunately I didnt have any fresh coriander (bloody tescos run out as usual)
The final curry was good, and my wife said it had the taste, but it didnt have that same savoury, yum it all down quality of my local BIR.
I think the oil is key and I will try this again with a slightly different base, I would keep the base the same as above but just add 1 TSP curry powder to slightly spice the oil more. As a side note I have never really noticed MSG add anything to a curry
