cooked 2 off further balti (plain chicken) both with the squat chilli added and 1 with methi added.
i fine chopped the squat green chilli and added to the oil per the adil video. the fine chopped worked a treat but will try adding after the base next time (just a preference).
the methi was disappointing - made the dish darker - pic below. i also felt the clarity of the flavours was masked (used 0.5 tsp). added it after the base per the adil video. i feel it is used in the meat balti but not convinced it's used in the plain balti. i'm dropping it.

i'm pretty happy already with the result. for me it's an 8 with the adil a 10. i don't have a feel on what would bridge the gap except for making it more and gaining that understanding of what slight variation does as i get a better feel for the dish.
things on my mind though being:
1) balti sauce - from meat cooking. this could play a part in the plain or chicken balti dish
2) ginger - i'm not using any and this could be wrong
3) i'm was getting too much smokey taste and have reduced oil back down from 6 tbsp to 4 tbsp. i'd like to get balti dish to try out the pre heating with oil
4) like to add back in fresh garlic in place of bought paste
5) can the garlic powder be reduced to say 1 tbsp - feel it's causing sticking around pan rim
6) need to get Bengali Bob's stock cube
7) for myself to add in the crushed red chilli - just to get a madras hotness
8 ) would pre cooked par boiled service onion work
9) long term perhaps need to work on a balti base
10) need to exclude "white" cumin - the adil cumin looked grey and not like i've seen before
ps have now got 100 Balti book and feel it has learning to be gained which will help the journey and close the gap further.
well pleased and will make this dish regular from now on.
