Lemonhead Lemon Candy was invented in 1962 using the same cold-panning process Ferrara developed for their cinnamon Red Hots. Starting with a sour center in a revolving pan, ingredients are added layer by layer until the candies reach the desired size. Ferrara has since added flavors and textures to the Lemonhead family, including Chewy Lemonhead, Lemonhead & Friends, and more.
