Vinegar is the troll of cuisine. It spots something good and immediately initiates an agenda to interfere and corrupt. It's a pugnacious product and can drive innocent people to madness. This is exhibited by the apple cider version, which a quick perusal of the interwebs will show those who come into contact with it often becoming delusional, attributing such panaceal powers to it as
healing decapitation, curing plane crashes, stopping AIDS, and detoxifying the absence of good taste. The practice of not changing one's socks for months in tropical climates is not a recipe for good sauce. Why, then, foist this squalid fomentation onto mustard, or anything that hasn't wronged our species?
The entire Prohibition was based on the simple misunderstanding of this stuff usurping alcohol. If they had only known.
