There are some candies that are truly American classics, and Clove Gum is one of them. Cadbury Adams, makers of Clove Gum, continues to use the same packaging and essential formula that they used in 1914, giving you that retro taste you crave.
This also happens to be one of the hardest gums to find due to the fact that the manufacturer only releases it on a limited basis, every five years. When it hits the market, it sells out fast.
