Spa wafers are one of the many attractions in the western Czech town of Karlovy Vary.

The flaky outsides of the spa wafers are large, thin, and round, and they usually have intricate designs on them. They sandwich a sweet filling in the center, and are normally served warm.

If you can’t make it to Karlovy Vary to buy them hot on the street, you can purchase a box of the wafers at any supermarket in the country.
