Conspiracy theory: 'spaghetti carbonara' is so named for the Carbonari, the italian pseudo-rosicrucian secret society also known as 'coal-burners', who popularized various pasta dishes as an edible encoding of their philosophy
@enkiv2 the mention to Carbonai as the secret society is in the English wikipedia page (but not in the Italian one), it would have made a much more exciting origin story tbh https://en.wikipedia.org/wiki/Carbonara#Origin_and_history
Yeah. Though, it's not like encoding philosophical, mystical, or religious ideas in food is terribly unusual.
The catholic mass's bread & wine is a normal invocation ritual (where you eat the symbolic godflesh in order to become the god).
Judaism seems to have a whole variety of symbolic meals with complicated symbolism that links to historical events. Hinduism has traditional foods for puja too, less linked to particular days.
