Actually, I was going to point out that growing up I'd eat the nuts extracted from the cone of the Araucaria tree, which - depending on shape and how ripe they are - could look remarkably like a green pineapple [1].

... but that introduces another issue, because I grew up eating those in South America and it turns out the tree originates in Australia. But it's not unthinkable that a similar pine cone could be found in Europe (and the vast Roman Empire of the time).
