curryhell,
appreciate you're interest. me too on some of the BIR but i doubt i'll be happy.
was quite interesting on making the dish - where to start.
i based on the lenny henry video except for the method preferring what i know ie hot fry.
recipe: dish01
fresh veg oil 1 chef 4 tbsp
black cumin seed 0.25 tsp
garlic paste 1 tsp
methi lg.pinch (thumb 3 finger)
chilli powder 0.25 tsp
chopped fresh tomato 1 off
base 300 ml (150 ml water added to thin ie 450)
fresh coriander lg.pinch
lemon dressing 3 sec squirt

thoughts on dish 1: cumin was bitty in mouth, tom too coarse, probably needs onion and green pepper, spicing was a little flat. the taste was very clean and pleasant - not there but a decent starting point something like 3 out of 10
dish 2 (still 3/10 - essentially went a bit off)
1) ground the black cumin and added with spice ie not in the oil at start - lost the taste though
2) used tin chopped toms - better on no lumps but taste was not as good
3) used x2 lg.pinch methi - too much
4) used x2 lg.pinch fresh coriander - ok can't say was better though
5) added in 0.5 tsp bassar - not sure. it filled the spice gap but the clarity of taste in dish 1 had gone (could have been down to the other changes)

nb color of both dishes was same and more like dish 2
thoughts going forward:
1) try repeat dish 1 with chef garam and garlic tarka at end
2) add some pre cooked chopped onion and maybe slice green pepper
any other thoughts appreciated. have 2 portions base left.
