Been asleep over here. To answer some of the points made.
Food colouring, as I said, is not something I ever do, other than very rarely in Tandoori Chicken. I saw the video on a chef putting red food dye powder in the batch of Tomato Sauce and just thought I'd see how much liquid dye it would take to change the colour of a small dish. Purely experimental and judging by the response here it won't be something I'll do too often in the future. Also note that the photos you are referring to were cooked during the early evening and taken under artificial light, whereas the Book Version was made in the mid day under natural light. This makes it seem much redder than it actually was.
JerryM:- The sauce from the Book Version eaten on it's own was delicious. There was left over after I'd taken it out of the pan and into the takeaway foil tray so I ate it. Yum.
The ingredient list for both preps were exactly the same.
Fresh300 grams Chicken Breast
3 Small onions (2 medium)
3 Tbsp Tomato Puree (not Paste)
1 tsp Garlic Paste
1 tsp Ginger Paste
1 Green Chilli (seeded and chopped finely)
Juice of 1 Fresh Lemon
Whole Spices (only the curry leaves were called for in the original recipe list)
1 Green Cardamom Pod
Tiny piece of Cassia Bark (only 1" by 1/4")
4 or 5 Black Peppercorns
Pinch of cumin Seed
4 Curry Leaves ( I'll have to check back on what I did to recall when I used these. You might see them show up in the pics.)
Powdered Spices1 1/2 tsp ground Coriander
1 tsp Kashmiri Chilli powder ( I only used 1/2 tsp as I needed my family to try it)
1/4 tsp ground Fennel Seed
1/4 tsp Tumeric
large pinch ground fenugreek
Other1 tsp Salt
300 ml Water
Vegetable Oil as required / preferred
Chopped Coriander leaves to garnish (optional)
Book Version (dead easy / bordering on lazy)
Essentially the tomato puree, water, lemon juice and all the powdered spices are combined in a bowl and set aside.
Cut up the onion and fry in oil, adding the salt and G/G pastes part way through the cooking. The original recipe here did not call for any whole spices but I put them in at the frying stage just so both dishes had all the exact same ingredients. I guess they should be fried off first to season the oil. I didn't as they were an afterthought part way through.
When the onion is done (clear) add the chicken pieces and fry off for 2 minutes to seal.
Add the tomato Puree mixture and stir through while bringing up to heat.
Cover and simmer for 8 - 10 minutes.
Garnish with chopped green chilli and coriander if used.
BIR Style (required extra water for Base Gravy)
Note:- this version actually ended up with only about 1 full onion in the final dish as I did not use anywhere near the full amount of Base Gravy. This probably explains why the Book Version is a more robust dish.
You should be able to follow the pictures.
I used 1/2 an onion and part of the tomato puree along with a bit of the salt, 1/2 the G/G paste and the whole spices, turmeric and mix powder to precook the chicken. Small amount of oil and water to cover. This took about 20 minutes.

http://www.curry-recipes.co.uk/curry/index.php/topic,13291.0.html#new I used 2 whole onions to prepare a small batch of AP/JV Original Base Gravy, very thin.
I then used the remaining 1/2 onion, G/G paste, powdered spices and Tomato puree to Tarka.
Added spoon by spoon Base Gravy till I had what I thought was enough sauce in the pan.
Added the pre-cooked chicken and heated through.
Garnish and serve.
(note) judging by the above feedback, do not add RED PILLAR BOX colouring agent.
I'm not even sure this is "Balti". The book in question describes Balti style as mild curries then gives recipes for "Balti Madras" and "Balti Vindaloo".
