Oreo is a type of chocolate sandwich cookie produced by Nabisco since 1912. In Europe, they are produced in Spain and Ukraine.
Oreo consists of of two chocolate wafers filled with a sweet creme.
In origin, the cookies featured a wreath around the edge and the name in the center. Main ingredients are sugar, Dutch-process cocoa, chocolate liqueur and flour.
There are many theories about the origin of the name Oreo, one of which is the derivation from the French word ‘or’, meaning gold, due to the fact that early packaging was golden.
Fun fact: in the United States, they were originally sold in cans with clear glass tops, so that you could see the cookies inside.
