Call me naive, but honestly never made the connection between swiss cheese and Switzerland.
Switzerland is an entire country with sodding great mountains and lakes, multiple towns, cities and a lot of worryingly loved leather clothing.
How on earth can you reduce a nation that supplies the rather lovely Swiss Guard to the Vatican and rather a lot more (that word is working quite hard at this point and perspiring very heavily) to the entire world to ... cheese.
I suggest you don't apply for any jobs in marketing. Your talents will be wasted, should any be found 8)
Swiss cheese usually refers to Emmentaler. It comes from the Emme Valley, in Bern canton. It’s delicious and one of the OG three of Depression-era fondue. (Gruyère and Appenzeller. Vacherin can come too.)
It’s called Swiss cheese because Wisconsin has a sizable 19th century ethnically Swiss diaspora. (Wisconsin also has a diaspora from Parma. It’s suspected the soft cheese they make is closer to what Parmesan was before WWII than Parmigiano Reggiano, though I personally find the latter tastier.)
That is... staggering to me.
OTOH, I have seen people genuinely ask "why is the Mexican language called 'Spanish'?"
