Hi Jerry, I could see the potential of this base but I made some mistakes and assumptions that took the edge off mine. I didn't make mine upto the correct volume (should be at least 6.5 litres +) and I think due to chef spoon measurements I overdid the g/g and spices. I did use some evaporated milk in mine.
The spice mix is good as is the curry powder. I'm sure most BIRs don't use Chinese curry powder but I guess the chefs at ifindforu's place made a lucky discovery.
I'll give this a go again soon, and think I'll adopt your way of adding extra oil to the base and reclaiming it before blending. Then I'll start my curries with the reclaimed oil. I don't see me ever using old bhaji oil.
Cheers,
Paul
