Post-columbian fruit is underselling just how new at least posts of it are. Carbonara was invented by US soldiers in the 1940s, literally made using bacon and powdered egg from their rations.

Tiramisu is unclear, but 1939 seems to be the earliest of the possible candidate, the earliest actual document is from 1969.

Pizza as we know it today was reimported from the US.

I love Italian food, but it’s much less traditional than people pretend.
