Having only had a Korma once in my BIR career, and that being decades ago, I thought it only fair to give a recipe a go to see if I was being unduly critical of it, given its unquestionable popularity in BIRs.
I had no recipe as it's the easiest curry in the world to make but included base sauce, sugar, coconut block, almond meal and cream. I deliberately held back on the sugar, making it sweet but not nauseatingly so as I taste tested while cooking. No pic as it just looks like every other generic Korma, i.e. like someone emptied the contents of their baby's nappy onto the rice.
Verdict - well, it started off bearable enough but after the third or fourth mouthful I was almost starting to heave. Despite deliberately curtailing the sugar content to well below that of a normal korma it was just too sickening for me, perhaps due to the added cream content.
So it's still a big, fat, no way would I ever eat this again for me. And, to add insult to injury, I had no almond meal but did have almonds so I ground a few in my favourite grinder which had a slight crack in the plastic cup and the damned almonds widened the crack and blew out a small piece of the plastic.
Korma killed my grinder!
