Potatoes and cabbage have been sustenance foods in ireland for agesduring medieval times these ingredients were readily available to the common man. This classic irish dish combining these two ingredients into a rich and satisfying side may have originated as early as 1735, but the first reference to "Colcannon" Is known to be in cassell's dictionary of cookery in 1875. There are many variationssome including kale instead of cabbage, some with leeks in addition to the greens, and some recipes baked in a casserole. But no matter how it is prepared, colcannon is so common that a recipe is often printed on the back of a bag of potatoes. In this recipe, mashed potatoes, along with milk and butter, are added to cabbage that has been cooked with onion until tender. The result is a bowl of comfort, perfect alongside a corned beef dinner. Or, if you add some chopped corned beef to the colcannon, you will have a traditional english dish known as bubble and squeak.
