Since almost all Americans have come from somewhere else, we tend to
use a foreign word along with the English word for something when
trying to transform the ordinary into something special. A famous one
is a recipe we call Shrimp scampi and I just read a blogger call plain
white/button mushrooms from the grocery store Champignon Mushrooms.
Can you think of any other examples? I'm blanking, but I know there
are more.
