Prune plums hold their form well at oven temperatures and are much used in baking, for example in tarts such as quetschentaart and zwetschgenkuchen. They are the sole ingredient in the traditional powidl jam of Austria and the Czech Republic, and the main ingredient in schmootsch, a similar but spiced jam from Silesia. Fermented zwetschgen are distilled to make eaux de vie: zwetschgenwasser or zwetsch, zwetschgeler, and quetsch. Carlsbad plums are a candied zwetschgen confection named after Carlsbad in the Czech Republic. Szilvásgombóc and zwetschkenknödel are potato dumplings with a zwetschgen filling in Hungary and Austria, served as a sweet main course or as a dessert. At Christmas markets in Germany, for example the Christkindlesmarkt in Nuremberg, a zwetschgenmännla or zwetschgenweibla, with a walnut head, a body of dried figs, and limbs of prunes, is a popular treat.
