That is a surreal tale.
In a way it reminds me of some of the oddities of alcohol prohibition. In particular, a label on a large bag of raisins.
“DO NOT add raisins to a large container with four gallons of warm water, two pounds of sugar, and two tablespoons of brewer’s yeast, with a loosely affixed lid, and put in a warm, dark place, or fermentation may result in the creation of alcohol, which is an ILLEGAL PRODUCT.”
That is a funny tale.
Giving directions on how to homebrew alcohol as a “warning”.
Might be a good way to sell raisins, though.
As I recall, home manufacture of wine and beer was not prohibited.
PruneO recipe as well.
