The history of the traditional Czech spa wafers (lázeňské oplatky) goes back to 1856 when Karel Reitenberger started to produce them on a large scale. Their taste and shape have not changed since.
You can find spa wafers in other Czech spa towns, but those from Karlovy Vary are the most famous. The large, round, thin and delicate wafers come in many flavors (our favorite is chocolate) and you can buy them boxed or get them fresh from a street vendor who will even warm them up for you. To our disappointment, the chocolate ones unfortunately can’t be heated.
