Colcannon
Colcannon is a traditional Irish dish of mashed potatoes with cabbage. It is a popular dish on Saint Patrick's Day and on the feast day of St. Brigid. Colcannon is most commonly made with only four ingredients: potatoes, butter, milk and cabbage. Irish historian Patrick Weston Joyce defined it as "potatoes mashed with butter and milk, with chopped up cabbage and pot herbs". It can contain other ingredients such as scallions (spring onions), leeks, laverbread, onions and chives. Some recipes substitute cabbage with kale. There are many regional variations of this staple dish. It was a cheap, year-round food. It is often eaten with boiled ham, salt pork or Irish bacon. As a side dish it goes well with corned beef and cabbage.
