Although to be fair, “Oreo” does sound a lot more welcoming than “Hydrox.”
Hydrox is the brand name for a crème-filled chocolate sandwich cookie produced by Sunshine Biscuits. It debuted in 1908. Oreos however did not come around until about 1912. They were inspired by Hydrox and yet most people began to think that Hydrox cookies were the knockoffs. Compared to Hydrox, Oreo had a “tangy, less-sweet filling” and crunchier cookie, so that it better complemented milk.
Hydrox however, was in the market until about 1999 when it was replaced with a similar product called “Droxies.” The Carvel ice-cream franchise still sells ice-cream goods manufactured with “Hydrox” cookie crumbs, using the cookies’ all-kocher status as a selling pint since the original Oreo recipe uses lard.
