1st attempt was unfortunately DISGUSTING!

I tried this curry base:
https://curry-recipes.co.uk/curry/index.php?topic=674.0With a good pre-meat recipe (this went OK, so I'll move on).
My 1st attempt was a Madras... simple enough I thought!
Heated 6 tbsp of oil until it was very hot, bunged in the spices for 20 secs, followed by some garlic paste and tomatoe puree, quickly followed by some base and the meat.
What I ended up with was not very flavoursome at all, VERY VERY dark brown horriblest curry I have EVER made. Yuck!
My conclusions: I think I have burnt something somewhere. I cannot explain why the curry I ended up with looked so horribly dark brown. I think it may have been the tom puree.
Also, I do NOT think that particular base is for the Madras type curries, to me the consistency is more akin to Korma / Massala dishes, hence to make matters worse this crap I cooked up just now was also stodgy.
Stodgy, dark brown, burnt, crap / no flavour. HORRIBLE.
Damn it! I was soooo looking forwards to a huge improvement....
Whaddya reckon guys, put me right here! ;D
