My first curry was a chicken Madras from a little place in Kinross around 1999 / 2000. It was like molten lava. I daren't think what their Vindaloo would be like. Anyway, I went back about a year ago and got one. It was nothing like I remembered. It was just like a remarkably average hot Madras recipe for here. It was the same chef and everything. Next time I was in I asked if they changed their recipe. They said they had not. I would suggest that when I reminisced about the curry, my brain put a bit of a silver lining on it.
I certainly think that the old school guys on the forum are looking for something different to what they're making but perhaps a little less different than they think?
Making as many curries as I do, to the very high standard that the recipes on this forum allow, I'd say I've developed a bit of an educated BIR curry palate. Places that I used to think make great curries are often now just so-so but nothing about the establishments appears to have changed. Could this improved BIR curry eating palate contribute to member's feelings of places going downhill? I mean, you'd have to be buying BIR all the time to go through nearly as many curries as you do when you're knocking up base sauce batches left right and centre!
Alternatively, the chef at that little place in Kinross just made me a shit curry! (no pun intended)
