Thanks SD - yes, definitely no burnt taste, if anything it seems to have cooked most of the flavour out of the base leaving only the taste of chili which is strange as I didn't add a lot of chili to the base. No mango chutney here sadly, I usually make my own but with three curries, nearly 100 bhaji and 60 naan to make, I'm not going there today

I might try some palm sugar or jaggery in it but then it is going to taste like nothing anybody will have tasted before!
Wondering whether to go with a Pathia now in the hope that the jaggery and tamarind paste will mask most of the bitterness - though I did that last time and wanted to go with something different, decisions decisions. Going to play around with single portions of different dishes and will try the lemon or some tamarind in a masala and see how it goes. Have given myself until 2pm as the cut of point whereby I'll have to either run with it or head to the shops...
Thanks again everybody.
