I don’t know if it’s going to be branded as a 100th-anniversary edition, but the Hydrox sandwich cookie (1908-2003) will return to store shelves (briefly) in August, and from there to my pantry.
Note to you stragglers: Hydrox was here first. The Oreo dates to 1912, although weird variations on the theme are a relatively recent phenomenon.
