I was laughing at that myself. Guessing this is something that sounds way better in the author's native language.
Yeah seasoning in italian never means “adding spice to some food” but only “keeping it in a cold/dry place and wait for it to be ready“ (usually months, sometimes years).
Good to know, thanks! I guess the term in english would be "maturing"
Curing?
aging?
marinating.
The term in English is... season[0].
Look at the second definition for the transitive verb.
