To be honest if I ever made it again I'd probably drop the oil to 150-200mm myself. And as you said, the curries you are trying to replicate are "not overly oily". I like to start off any curry with oil, if only reclaimed from the base itself or pre-cooked chicken as I like to tarka the G&G and mix powder to mellow the flavours before "building" the dish so to speak. It's a nice base and the subtlety leaves room for extra spicing to suit your tastes. My madras is as follows.
3 tbsp Oil (skimmed off the top of the base if using the original recipe amount!)
1 tsp Garlic & Ginger Paste
1 tsp Mix Powder (you could also get away with up to 1 tbsp in this base)
1 level tsp Methi crumbled fine
1 tbsp Tomato Paste (1 pt tomato puree 2 pts water)
2 tsp Extra Hot Chilli Powder (or to taste)
Pre-Cooked Chicken (I quite like the Glasgow recipe)
Salt
2 ladles Base Gravy
Squirt of Lemon Dressing
1 tbsp Fresh Coriander finely chopped. (1/2 Stirred into the curry two minutes from the end and 1/2 sprinkled on top)
You know the rest!
