Chewytikka,
yes pre cooked are 0.25 tsp turmeric and little pinch salt, simmer 10 mins in water to just cover. they work well - had inconsistency in past trying to fry fresh at dish frying.
i don't use any colouring.
the bahar comes down to what the guess is for the tom puree - i used secret santa chilli sauce which i use for madras. the best i can describe a bahar is a mix of madras and jalfrezi. if tom puree was used then it's not bahar and no rename.
i was well pleased with the overall taste and taken aback by how the individual tastes show through too. i did not add meat so that i could really get the taste of the sauce - it was spot on and see noting to improve other than the green sauce but even that's very fine tuning.
should point out that i pre fried the sliced onion/green pepper before starting the dish and placed in a bowl until adding back at the end. i would normally pre fry a batch in the wok.
many thanks.
