Colcannon is a lovely Irish comfort food combining potatoes and cabbage, all mashed together. It can be served as side dish, or if you add sausages it can become a main course feast.
At Halloween, it served to predict marriage. Charms were hidden in the mashed potatoes and any unmarried girl who found one would place socks with spoonfuls of Colcannon and the charms on her front door handle. The first man to enter the house was her intended.
