Heat and time also cause chemical changes, CC. In particular, a change away from the original taste.
I find that things heated up (not just curries) just don't have the same fresh taste, although the 'depth' (or complexity) may well have changed. I can honestly say that personally I have never had a curry which tastes as good as or better than the original when reheated the next day. It tastes OK, yes. But it tastes different.
At best, the spices might be more pronounced - and I wonder if that's what people are latching on to? But I find the garlic and fresh coriander tastes are less and there is usually a bitterness that wasn't there before (or is it a missing sweetness? I don't know).
This happens with curries from my favourite restaurants and with those I cook myself.
The other thing to consider is that since the curries we are all apparently looking for are cooked fresh, is the subject of reheating them the next day connected with finding the secret or not?
