JerryM, Im not sure on the ginger amounts/usage ,I feel I have gone full circle on the use of it in a base sauce. Gone from 50/50 to 60/40 in favour of garlic to 30/70 in favour of ginger, which actually created the most bir smelling base I have made after a slow long onion stage cook.
As for the final dish I am currently at the stage after tonights curry that less is definitely more on the ginger front (if any at all) for madras or vindaloo anyway. Maybe the base needs a higher ginger ratio and the final curry no ginger at all. Just thinking aloud.
