Roudoudous are traditional candies originating from France. These sweets were especially popular from the 1950s to the 1970s, when local confectioners drizzled fresh caramel or fruit-flavored syrup into a seashell and left the concoction to harden.
Roudoudous were one of the favorite sweet treats for children, and nowadays, the commercial versions are usually sold in plastic shells. The sweet treat is enjoyed just like a lollipop – by licking it until it disappears.
