Fun fact about chocolate. Much like lots of things in the New World, Europeans were extremely suspicious of Chocolate, and practically ignored it for a long while, especially because the native word for the plant, Kakau, sounded suspiciously like the Spanish word for "poop", caca, so of course they weren't keen on drinking the suspicious brown drink they were offered.
Similarly, Tomatoes were imported into Spain and Italy from the New World, and were used in food, but the rest of Europe thought Tomatoes looked suspiciously like a family of poisonous fruit called Nightshade, and refused to eat it, concluding it wasn't fit for human consumption (all while Spain and Italy were developing different cuisine with it)
There's also a bunch of other stuff Europeans missed out on by being dumb, that I honestly think that if plague hadn't wiped out 95% of the two continents, they would have never been able to colonize the region like they did.
