Þorramatur (Thorramatur, food of the þorri) is a selection of traditional Icelandic food, consisting mainly of meat and fish products cured in a traditional manner, cut into slices or bits and served with rúgbrauð (dense and dark rye bread), butter and brennivín (an Icelandic akvavit). Þorramatur is consumed during the ancient Nordic month of þorri (Thorri), in January and February, particularly at the mid-winter feast of Þorrablót (Thorrablot) as a tribute to old culture. Being thus connected with the tradition of Þorrablót festivals, Þorramatur is most often served as a buffet.
The idea of connecting this kind of buffet to the month of Þorri and the Þorrablót festivals, which had been held by many student associations since the late 1800's, was of the restaurant Naustið in Reykjavík. In 1958 the restaurant started advertising Þorramatur, which is the first mention of the word in Icelandic texts. The food was served in large wooden troughs, containing enough food for four people, that were copies of old troughs that could be seen at the National Museum of Iceland. The idea, according to the owner, was to give people who were not members of a regional association the opportunity to taste traditional country food. It was also an attempt to revive an otherwise rather dull season for restaurants. The attempt was successful, as the idea immediately caught on and boosted the popularity of Naustið, even though it was quickly copied by other restaurants. Very soon, many of the regional associations and the student associations which organised Þorrablót festivals every year, started serving Þorramatur buffets at their events.
Þorramatur has undergone many changes since the 1950s. The large midwinter festivals of associations in Reykjavík have been supplemented by many smaller ones and nowadays even informal family gatherings can be called Þorrablót, which has become defined by the serving of Þorramatur, i.e. the consumption of Þorramatur is the necessary and sufficient condition for any kind of party to be called "Þorrablót". Originally, this led to the standardisation of the buffet around a few foods mass-produced by large meat-production houses for the Þorrablót season, whereas before it often had to be locally procured. Not least, Þorrablót festivals have become one of the high points of the year in the rural countryside and villages around Iceland in the last three decades. Being thus exported from the city to the countryside the buffet has come to reflect again regional culture and traditions.
Þorramatur has also changed to reflect changing tastes. The traditional method of storing meat by laying it in lactic acid, which gives the food a characteristic sour taste, is unfamiliar to most generations of Icelanders living today and therefore a Þorramatur buffet usually has a choice between sour and unsour pieces of the same food, served on separate trays as the acid readily contaminates food it comes in contact with. Some of the food, for example the rams' testicles, has to be cured by the acid before serving though. A number of foods have been added to the buffet that have never gone out of fashion in Icelandic cuisine, such as smoked lamb, fermented shark and dried fish, which are still commonly consumed in all seasons. Þorramatur also has included some novelties, traditional food that was strictly regional and even rare as such, and unfamiliar even to the older generation. Examples include seals' flippers, known only from the Breiðafjörður area, which is sometimes, albeit rarely, served as part of Þorramatur.
During the month of þorri, þorri buffets are quite popular in Iceland where many restaurants in Reykjavík and elsewhere serve þorramatur which is almost always served on wooden platters, called trog (trough). At these gatherings, Icelandic Brennivín is often consumed in copious amounts.
