Years ago, a local Mexican restaurant featured a scrumptious dish of chicken cooked in a mild but very flavorful brown sauce. It may have contained some chocolate but it was not a mole.
Once, and only once, I found a jar of something called 'Nun's Sauce' that came close.
I have seen recipes labeled 'Nun's Sauce'. These are interesting but they are of British origin and are relish-like concoctions more suitable to roasts than to chicken cutlets.
Any ideas, anyone?
