Three mysterious candy finds for your consideration:

Sen Sen, the nation's oldest breath freshener, immortalized as a sign of Trouble in River City in The Music Man, is still sold online and in a few little shops here and there. The mystery? How this acrid, licorice-tinged mint survives on the patronage of its tiny cult following.

Remember honeycomb candy? Here's another example, coated in chocolate. The mystery here is how they created the airspaces. Unlike traditional honeycomb, where the bubbles are created by baking soda and acid and form a random network of toffee, this piece appears to have had air machine-injected somehow. Still tasty, but the traditional kind has a much more satisfying crunch and chew.

Finally, these fascinating rice paper pockets filled with tiny sugar spheres. The bland pastel packets crunch under the teeth but dissolve on the tongue, loosing the chewy Dweeb-like candies inside. Odd, but surprisingly good, I have no idea what to call these rattling candies. Anyone have a clue?
