Rum balls are a truffle-like confection of sweet, dense cake or biscuit
material flavoured with chocolate and rum. They are roughly the size of a
golf ball and often coated in chocolate sprinkles, desiccated coconut, or
cocoa. As their name implies, these cookies contain rum. Because they are not
baked, the alcohol flavour and kick are not lost during preparation. This
cookie is especially popular during the holiday season.
Rum balls are a popular Christmas treat in England, Australia, Canada,
New Zealand, the United States, Austria, Slovenia, Hungary, the Czech
Republic, and Denmark (where they are called romkugler and enjoyed all the
year round).
