A bit more info about what I cooked.
I made my standard favourite chicken curry:
Pre-cooked onions and green peppers fried in mixture of butter ghee and coconut oil. 500 ml of Abdul Mohed's base gravy (the only one I have at present), 4 cloves garlic finely chopped by hand, lesser amount of ginger, 1 tsp tom puree (diluted 3:1 with water), I usually use more but this base is quite tomatoey, a pinch of methi, half teaspoon kashmiri chilli powder, some salt, fresh chicken breasts, finely chopped coriander stalks and some leaves and 1 tablespoon of the mystery mixed powder.
All I can say is that the spice mix from ifindforu produced a superior curry to what I normally manage to cook. It is hard to describe but words like more refined come to mind. Less harsh and more fragrant than my normal curries, which I was already pretty pleased with. My wife totally agreed with this opinion.
It was certainly a lesson to me that there is still some mileage for improvement in the mix powder, I've tried loads of mix powder recipes and I imagined that any improvements for me would probably come from the base sauce recipes.
It would be great to hear a second opinion - I don't know whether anybody else (like CA or JerryM) has been sent the same spice mix. If it was for sale on ebay at a reasonable price I would certainly want to buy some!
Of course it would be nice to know the recipe but thanks anyway to ifindforu

Cheers,
Paul
