Hey guys, well like many of us (given his great curry pictures), I was excited to try out CA's recipes. I actually bought scales for this. Here is my attempt at CA's base gravy and Madras, to which I added a few extra veg ingredients at the curry stage (whole deseeded finger chillies, 1 tbsp finely chopped green capsicum, 1 tbsp finely chopped onion, 1 fresh tomato quarterd and a little extra garlic - you can see in the pictures) to create a Bhuna Madras. Other than the changes mentioned, I stuck exactly to the recipe (oh, I used chopped Coriander leaves rather than stalks / roots - I don't care if it looks green).
Stage 1 base ingredients:
Added spice mix and Coriander
After blending:
Ingredients for curry ready
Finished Curry
Curry and Pillau Rice ready to eat 
I had great success with this recipe. The best results I've had in a very long time, possibly ever. This really worked for me. The result was just like my best local takeaway. I'm very happy with the base and think the spice mix suits me perfectly.
ObservationsThe base is thinner than what I'm used to. It also asks for small amounts of things like green capsicum and carrot - less than most other I've seen. I was dubious about the use of sugar. I've added some to a base before and it turned out to be a bad move. However in the final recipe I did add the 2 tsps which were called for. Worked a treat. My picture of the spice mix didn't come out well but mine looked lighter than CA's. I can't explain this, as I stuck as precisely as I could to the recipe. Maybe just a crap camera?
I'm very glad that I tried these recipes. They are excellent. Thanks very much CA!
Having cooked the base, I have since realised that I should have added the Coriander
after having cooked with the spice mix for 5 minutes. I seriously doubt this made any difference as the base gets cooked again when the final dish is getting made, making any argument for loss of freshness of the Coriander or similar unlikely.
