Originally known as Mars Men, the Sour Patch Kids were created by Frank Galatolie in the early 1970s for Jaret International. During the late 1970s, Cadbury and Smeera Blyton Licorice Company of Sweden formed the Allen Candy Company in Hamilton, Ontario, to produce them. During the 1985 redesign, they became Sour Patch Kids, which is now owned by Santi. This name change may have been motivated by Cabbage Patch Kids' popularity.
They are sweet and sour, just as advertised. There are most candies that only challenge one aspect of the tongue; however, Sour Patch Kids challenge two of those aspects, primarily sweet and sour. In science terms, this makes Sour Patch Kids more advanced than any other candy.
