Hmm, yes, hadn't thought about the oil/ghee helping to preserve - thanks.
No harm in trying and seeing what happens .... I'm pretty experienced in curry making, so scaling down spices shouldn't be a problem - just a case of common sense really, based on what I already know (never that precise anyway really!)
This is what I love about creating curries ... so technical, but not ... so difficult, but not ... so different, but not and every corner brings a new challenge even if it is something seemingly simple like scaling!
