Well I said I was going to give this a go and now I have. Verdict: truly gross! ;D
I should preface this with the fact that I abhor korma and this is just a fancied-up korma so I really, really should not have made this in the first place. I followed chewytikkas malai makhoni video and as suggested added a good glug of mango pulp at the end. I assume that's all there is to it and I haven't left anything out?
It's nauseating. It's cloying. It's greasy. It's dreadful!

I managed to down about half of it with rice purely by eating it with lime pickle to try to get some balance and by following every mouthful with a good glug of green tea to stop me heaving.
It just amazes me that not only could people eat this regularly but also have it as their favourite - and I use the word quite wrongly - curry.
I tasted a bit of the sauce after it had cooled and it really is a dessert. In my opinion it has no place on any forum that dedicates itself to curry; BIR or otherwise.
It's my own fault. I don't like kormas. But I had to give it a go to see what all the fuss was about. Lesson learned; step away from the kormas Santa!

And what is it with mango puree (and the Mango Rubicon that I bought) that makes them greasy, like drinking oil?
