I agree its a very overpowering, yet flat & sterile taste that is very hard to not notice. When you make a v good Curry its the only thing that stops it being a perfect Curry , even i use less to achieve the taste i require, i find 12 green Bird`s eye chillies with with 2 Desert Spoons of extra hot Chili powder ( for a 3 Curry batch) will give the heat but even then there is that underlying flat taste, thats why I'm also using for fresh Tomatoes to give that sour/sweetness in my Vindalloo/Tindalloo with some salt & i get a very good balance ;D
