I'd give it a try if I were you BB,like CK says you haven't anything to lose, and you may gain a lot.
I watched my friend prepare his base yesterday but hit a problem almost straight away when I asked him the quantities of each ingredient as his answer was "I don't measure, I just know".
Of course I came home and tried a rough scaled down version trying to equate the quantities I saw.
I use an extra hot chilli powder and so misjudged the amount when using the base to make a madras, the curry tasted fine but nearly blew my head off, I'm going to remake the madras tomorrow using a smaller amount of chilli powder and force 2 of my friends to test it for me.
His base is quite simple compared to some and he uses a LOT less oil,just enough to put a film over the base is the way he put it.
Its a waste of time me putting the base up at the moment because in the final 10 minutes he turns the heat up and adds his 'masala mix' and I haven't yet coaxed the recipe out of him.
I also need to work out a definitive scaled down version depending on the outcome of future taste tests.
My wife is already sick to the teeth with eating curry and being my 'taste tester' ;D
