So I'm now pondering the difference between "An Even Better Curry Base" and the ULTIMATE curry base. Ultimate, in being the absolute best achievable, is a very strong claim.
The recent base I made followed a very basic recipe that was apparently restaurant used in the early BIR days. Nothing but Onions, G & G, Tomato, salt, turmeric and paprika, water and very little oil. Using this, and an equally basic onion paste, produced finished dishes that I was quite happy to have cooked. It's use also produced a very nice pre-cooked chicken. It all worked exactly as it should.
Does the inclusion of trace amount vegetables, coconut and extra spices, or the variation of oil ratio, or changing the cooking process from a 1 hour boil and blend to a half-day, 3 pot marathon really produce a better sauce or just a different one?
