This confection features a hard candy shell, typically flavored to replicate the tartness of a specific fruit, combined with a soft, often chewy, filling made from cooked sugar. The exterior provides initial flavor impact and structural integrity, while the interior offers a contrasting textural and flavor experience. The presence of the filling distinguishes it from a standard hard candy, adding a richer, more complex profile. An example would be a candy where the outer layer evokes a crisp, sour taste, and the inner layer provides a smooth, sweet taste.
The appeal of this treat lies in the interplay of textures and flavors. The initial hard exterior gives way to a creamy or chewy interior, creating a satisfying sensory experience. Historically, such candies have been popular due to their long shelf life and portability. The combination of contrasting flavors, such as tart and sweet, appeals to a broad range of palates. The individual components also often use ingredients or processes that provide extended shelf life.
