Icelanders tend to hold on dearly to traditions of all sorts. Some traditions are familiar such as folk dancing but others are more foreign to visitors. First there is our traditional seasonal food. The desire to eat what might be considered damaged food, but really is food that has been processed for storage in the only way that was available centuries ago. Also in a poor country were food was not of plenty, it was essential to use everything eatable and available (which today is debatable.), those things include ram´s testicles, sheep´s heads, loins and basically the insides of the sheep, usually cooked together in sacks from the stomach or intestines and called Slátur, much like Haggis in many ways.
When it was time to mark the end of winter and beginning of spring people use to selebrate by feasting on this type of food – This is called Thorrablót and is still selebrated today by Icelanders where they feast themselves on soured foods, smoked hanged meat(hangikjöt), sheep´s heads and all the other delicacies that tradition offers.
There is a nother tradition of sorts that is a bit more plesent and in reasent years has taken on a more international feel. In Iceland we have not one but thirteen santaclauses. They are usually reffered to as the yule-lads. They live up in the mountains and come down, one at a time, the first one coming 13 days before cristmas. They go from house to house leaving little treats in childrens shoues which they place in the window.
