I feel very strongly that you should use the moister brown meat, from the thigh, for this, but if you prefer breast meat, and it's a common preference, that's your choice. I can't pretend to understand it though.
There is a long list of ingredients below - and I am not going to pretend this is the sort of food you can bang out in a moment. One ease-making factor to be borne in mind: not only can it be made in advance, it needs to be; only if you let it steep in the pan, in a cold place in the kitchen, overnight, does it have the full depth and resonance of flavour.
