Rumtopf (Danish: Romkrukke), which literally means rum pot, is a German and Danishdessert, traditionally eaten around Christmas. Once a popular traditional dessert, Rumtopf has become rather unfashionable in recent years.
A mixture of various kinds of fruit, high-strength rum, often Stroh's, and sugar is filled into a large stoneware pot (the eponymous rum pot) and matured for several months until the fruit is very soft and completely saturated with rum. Suitable fruit includes berries, cherries, plums and apricots. Not all fruits are appropriate for Rumtopf, and the overproof rum should be of only 100-110 proof (50-55% alcohol by volume), which is not commonly available at retail in all regions, but can be prepared by blending more common commercially available 151 proof and 80 proof rums.
Traditionally, the pot is set up in a cool and dark place in Spring, and different kinds of ripe fruit are added to it over the months as they come in season. The fruit is thereby preserved to be eaten in Winter, when the Rumtopf is matured.
