While I love making individual curry portions from a base sauce - doing curry nights in my pub mean I have had to make up larger amounts on occasion.
In the past I made big 1 pot all-in curries from various traditional curry recipes but found they were lacking in the BIR flavour that I was trying to achieve.
I then started making big pots of curries from 1 batch of KD base and multiplying my curry ingredients by 5-7 (except salt and chilli) and got some great results.
However making even larger curries involved a lot of guess work on the spicing and this method increased the number of cooking stages - 1 make base 2. pre-cook meat 3. Make up curry.
The beauty of big batch cooking is it is quite hard to really cock it up - and reasonably easy to rectify any problems (in comparison with individual curries anyway). There is a lot more lee-way either side with spicing, heat, saltiness etc.
So not sure you can qualify this as a BIR dhansak - though my intention was to make it as close to that as possible.
RecipeStarted by making 2 x Bruce Edwards base, which was quite brave as I have only used KDs in the past.
I did some multiplications of my slightly tweaked Gezh's Dhansak recipe and worked out I needed the following:
1 litre oil
2 x Bruce Edwards Base
1 kg yellow split lentils + 500g red lentils made into a basic dall
3 tsp salt
8 kg pre cooked chicken breast (just boiled)
30 tbsps Garlic/Ginger puree
300 ml tomato passata
spice mix30 tsp Madras curry powder
20 tsp Garam Masala
9 Tbsp Kasoori Methi
12 tsp amchoor
sweet/sour mix250 ml sugar
200 ml mango chutney
250 ml lemon juice
smokey/dark mix20 tbsp Ketchup
20 tbsp soya sauce
Chopped coriander 1.5 bunches
The method:I made the base the day before, and the dall which was a simple water, turmeric, lentils simmered for an hour till I got the consistency I wanted.
I then heated 3/4 of oil and fried the garlic/ginger puree for a min or 2
Then added the spice mix and stirred for another min.
I then added all the base and the cooked dall - and heated for a while to get up to temperature
At this point I added half the sweet/sour and smokey/dark mix and tasted till I got the flavour balance right in my opinion (I then whacked the lot in!)
I then poured the curry over the chicken - and chilled ready for the following day.
To reheat I heated to oil and slowly bought to a simmer - stirring regularly as the lentils tended to sink to the bottom and stick to the pan.
The curry turned out really well - needed a touch more chilli - but cooking for lots of people with various chilli tolerances means you have to keep it reasonably mild. Sold 40 portions and still had some left over to give little pots away for seconds!
Some naff mobile phone pics attached:

Lots of pureed base

Curry ready for re-heating - more smokey mix making it look darker

Lots of poppadoms

Serving on the night

Was too busy afterwards to take any pics - but it looked great on the plate - and we had lots of happy customers!
I had also made up a pot of veggie curry, a rice cooker full of pilau rice, a naga-chilli sauce to spice up the curry and about 60 poppadoms!
