Idk from where it is from but again we just call it pain perdu which translate to lost bread because it is a good recipe for old bread you forgot in the kitchen.
Last one is the normal kiss here and fun fact a kiss with the mouth close is called a smack
So yeah why does the american/english don't do more research about origins and call everything french ?
It's because deep frying was not very common in the U.S. Immersion in hot fat was considered a French style of cooking, so they're French style fried potatoes. I think "fries" instead of "frieds" is dialect that caught on nationally in the U.S. in the 70s.
