Øllebrød
Øllebrød is a traditional Danish dish. It is a kind of porridge made of rugbrød and beer, typically hvidtøl, and it is a thrifty dish. Traditionally bread scraps are used, so as not to waste any bread that would otherwise get trashed. The idea originated from monastic living, when monks would dip their bread into hot beer. Formerly Øllebrød could be accompanying all three meals throughout the day, but is now mostly eaten for breakfast only.
Nowadays commercially available instant powder mixes for making Øllebrød are available.
Øllebrød is usually served with plain milk, but sometimes whipped cream is used instead. Traditional recipes sometimes flavour the porridge with either lemon or orange.
