Hi all, (first post).
I'm no connoisseur, just trying to knock up an acceptable CTM. I've played around with Gordon Ramsey's vid version and am producing something that's sort of OK for me for the time being. Still experimenting.
However, 3 times now I've tried the base-type method just for a one off curry (didn't want to waste a lot of ingredients), but it always produces a foul odour - I believe it's to do with the garlic mostly and maybe the ginger too - that doesn't happen when I fry garlic+ginger with the onions in the Ramsey type method. No matter what I do with it afterwards; after adding tomatoes, and putting it into any amount of fried spices, the foul odour and *taste*, the like of which I've never encountered, remains.
What's happening to me?

Is it supposed to do this if you boil rather than fry it? I've never detected anything remotely like this smell and flavour in BIR CTM.
This is what I did for the base- type concoction:
Some veg oil in pan
Added 1 chopped red onion and some salt
Fried for a bit until partially caramelised (I've tried this to different extents)
Added 1 clove of freshly crushed garlic mashed up with a 3/4'' piece of root ginger and some water.
+ chopped green chilli
covered with water, brought to boil and simmered for 1 hour.
Then added tin of tomatoes and coriander and boiled for 15 mins before adding to the pan with oil, cooked spices, cream etc.
Halfway through the first hour the smell from hell arrives.
