Zu Zu Ginger Snaps was a brand of round drop cookies originally manufactured in 1901 by the National Biscuit Company (NBC) –later changed to Nabisco – and produced until the early 1980s.
The snaps are "a spicy combination of ginger and sugar-cane molasses"[1] and came in a distinctive yellow box with reddish type.
[3] In the 1946 film It's a Wonderful Life by Frank Capra, one of George Bailey's daughters is named Zuzu after these cookies.
[4] In Out of the Cracker Barrel by William Cahn (a book commissioned by the National Biscuit Company), the name of the product is said to have possibly originated from a character in the play Forbidden Fruit by Dion Boucicault.
Adolphus Green, NBC's first chairman, supposedly saw the play and adapted the name of the character "Zulu".
