I don’t think that I had anything like this from cartoons, but I had read about ginger beer in various childhood books long before I actually encountered it in the flesh and also Turkish delight from The Lion, The Witch and the Wardrobe, which was also one that I didn’t encounter IRL until later.
Ginger beer turned out to be a bit of a disappointment - not a patch on elderflower pressé, for example - but Turkish delight lived up to that passage, and I have thought about the book pretty much every time I have tasted it over the decades since.
I’d always suggest volunteering - be it wildlife conservation or staffing a charity shop or restoring vintage trains in a museum or whatever. Pick something that you have a little interest in and you will already have that in common with the other volunteers and, as a volunteer, you have no commitments and can walk away at any point.
