Hi Jakebodle
Welcome to the best BIR resource online. A true gem of a forum. Your experiences are common to many of us chasing the BIR holy grail. Honestly, if I still lived in the UK, I'd probably just give up and go takeaway / restaurant, although I do love cooking a curry. However, here in the US, I don't have the BIR option - only traditional Indian dishes are available to me which, while good and tasty, aren't BIR. they don't have that certain something.
I don't have the skills / experience to experiment with recipes and remember what I did, so am getting all analytical. I've started a spreadsheet to track each curry I cook, in an attempt to try and identify variances / consistencies in the ingredients. I lucked out with a vindaloo the other week that took me by surprise.
I will also include the various mix powders I try and track that aspect.
In the end, no amount of spreadsheetery (nice word) will cook me the 'proper' BIR vindaloo I crave but, hey, I get to think about curry a bit more, which is never a bad thing. I attach a Word doc with a picture of the spreadsheet to show the level of insanity obsession detail I'm going for.
Tomorrow's attempt is a Madras from the Glebe Kitchen website.
Keep calm and curry on.
