We humans like the familiar. I believe this is why some fast food chains are massively successful. When in a different country, some of the food will fall into the category of ‘acquired taste’. I have eaten things I wouldn’t opt for when I am in Germany, but some I still shun. No matter how much you try to sell it to me, fried cockroaches, fish eyes or pigs’ tails, I skip. Perhaps we would be more adaptive if the locals eased us in a bit instead of trying to find out what would be the most revolting thing for a tourist for the welcome dinner.
