Drisheen
Drisheen is a type of blood pudding made in Ireland. It is distinguished from other forms of Irish black pudding by having a gelatinous consistency. It is made from a mixture of cow's, pig's or sheep's blood, milk, salt and fat, which is boiled and sieved and finally cooked using the main intestine of an animal as the sausage skin. The sausage may be flavoured with herbs. Historically, tansy had sometimes been used as a seasoning for drisheen. However, it has since been discovered to be toxic to humans. The recipe for drisheen varies widely from place to place and it also differs depending on the time of year. Drisheen is a cooked product but it usually requires further preparation before eating. How this is done varies widely from place to place.
