i tried the onion sauce in Dipuraja's Balti. it tasted pretty good. i also made a mogul with it and felt the result poor c/w the spec pre fried. i have 2 off portions frozen to explore it's use further.
Balti is not the ideal test for it for me personally as Balti is one of the dishes i've never got right (alum rock road and the like version). my preference would remain for pre fried onion and green pepper slices.
i can see the sauce working in say dupiaza to give the soft onion part of the dish.
i am pretty sure 3 types of "onion green pepper" exist (par boilled chopped, pre fried sliced, curry2go sauce).
for home use and conscious of prep time i can't see me making it. it does add another layer of flavour - i just don't make the dishes where this would be needed.
well pleased i tried it out as it helps put my mind at rest on things made in BIR (pastes, sauces) that could end up on a selective basis in the various mains. red masala being a good example of overuse.
