Denmark, but being dutch vs danish is very commonly confused/conflated in the US :D
It is true though. Can’t count how many times I’ve had this exchange “Oh danish huh? I love Amsterdam!” (the dutch capital)
Europe is full of tiny countries and I absolutely can’t name all 50 US states or place even half on the map. No intention of shaming
