The other day I got to thinking longingly about my all-time favorite "store-bought" cookies, Hydrox, which haven't been available for years. They were so good, especially frozen! To this day I won't eat Oreos, which are overly sweet imposters. :)
A Google search soon showed I was not alone in my longing for Hydrox. I found websites (above and here) with Hydrox history and comments. There's a Wikipedia entry and even a petition asking that they be made again.
You really can find information about almost anything on the Internet!
