I think we can say a few things about curries from Ta's from our experiances so far.
1) They'll use only one type of basic stock/sauce to create most dishes.
2) The dishes only become different from one another during the stir-fry stage.
From here we can add more...
If the finished dish needs to be thick, reduce the sauce down during the stir-fry.
If it needs to be thinner, add more sauce, or don't reduce it for so long.
Depth of flavour, if we reduce a ladle of sauce right down, then it will have more flavour, if it needs thinning add more sauce. It will still keep the added depth of flavour because of the first reduction.
Personally i think your biggest job Jerry will be in creating or finding the correct Vindaloo paste for the stir-fry stage.
