Josh, CoR, Secret Santa,
some interesting thoughts to chew on (5 tbsp, 1/16" or 2mm, scooping off).
i'm still trying to taken on board the difference upping the oil had on the madras in terms of taste and ease of cooking.
this will keep me going for quite a while. i'm going to try 6 tbsp next and perhaps a 4 tbsp. the scooping off is also something that crossed my mind (we actually spooned some off whilst eating and i put this in my onion paste jar - perhaps wasted opportunity emm!).
the big thing is to keep the hits coming. i am pretty confident though that it was the oil all the time and that i was sort of teetering on the border line. there can't really be any other explanation (especially given the taste was there in the 2 off kasmiri curries which i did not expect or plan for)
