Trivia: What were hamburgers called during World War II?
Eagle patties
Liberty sandwiches
Freedom burgers
Knuckle sandwiches
The correct answer is Liberty sandwiches
So why is this answer correct? : While arguably one of the most popular foods to serve at a barbecue today, hamburgers went through some interesting rebranding during WWII. Throughout the war, Americans did everything they could to avoid referencing Germany, including the city of Hamburg, from which hamburgers gained their moniker. Instead, burgers were renamed “liberty sandwiches,” just as sauerkraut was called “liberty cabbage.”
