A wafer is a crisp, often sweet, very thin, flat, light and dry biscuit,[1] often used to decorate ice cream, and also used as a garnish on some sweet dishes.[2] Wafers can also be made into cookies with cream flavoring sandwiched between them. They frequently have a waffle surface pattern but may also be patterned with insignia of the food's manufacturer or may be patternless. Some chocolate bars, such as Kit Kat and Coffee Crisp, are wafers with chocolate in and around them.A communion wafer is a type of unleavened bread consumed after transubstantiation as part of the Christian ritual of communion.Special "spa wafers" (Czech: lázeňské oplatky, Slovak: kúpeľné oblátky) are produced in the spa towns of the Czech Republic and the Slovak Republic (e.g. Piešťany). The production of the wafers in Karlsbad and Marienbad was traditional to the towns' German-speaking population, who, after the ethnic cleansing of the area, brought the craft to Germany.[3] [Wikipedia]
