Many nondairy 'blue cheese' recipes are pepita based. It actually mimics blue reasonably well according to omnivores.
What constituent(s) creates this flavor? Recipes include acid and salt and sometimes yeast but where is the blue?
I've looked at short-chain fatty acids etc like propionic, butyrate, valeric (pentanoic), decanoic and lauric; even the goaty 3-methylbutanoic present in blue cheese. Doesn't correspond with pepitas palmitic, oleic, and linoleic so what could it be?
