01The answer
Roasted cacao and blue-mould-ripened cheese share five key volatile aldehydes. The Maillard products of cocoa roasting and the proteolysis products of Penicillium roqueforti cultures both build C5-C6 aldehyde backbones, creating overlapping aroma signatures the olfactory system reads as complementary.

03Traced to the literature
04What it does not claim
Shared aroma compounds predict that two foods will read as compatible. They do not measure how strongly you will perceive it: published concentration data does not exist for every compound in every variety. The Geist says so instead of rounding it up to certainty.
