Drisheen (Irish: drisín) is a type of black pudding made in Ireland. Irish black pudding is made from a mixture of cow's, pig's and/or sheep's blood, milk, salt, fat and breadcrumbs, which is boiled and sieved and finally cooked using the main intestine of an animal (typically a pig or sheep) as the sausage skin. The sausage may be flavoured with herbs, such as tansy. The recipe for drisheen varies widely from place to place and it also differs depending on the time of year.
