Hi chriswg, i made this base and madras 3 times this weekend , with varied amounts of water, to get the right taste from the madras. i quite liked the base, as its quick and fresh, although did not like the yogurt, too sour. Also too much plum tomato + chilly in the base IMO. the madras tasted like hot tomato and chilly + lemon curry. it is a million miles away from the subtle lightly spiced sweet/toffee madras sold at my fav bir. for me this was a step backwards. However i have learnt how to make base on the fly, which is useful. overall an interesting learning experience! ;D
