Colcannon is a traditional Irish dish of mashed potatoes mixed with cooked cabbage. Warm and comforting, this recipe comes to us from Darina Allen's Irish Traditional Cooking: Over 300 Recipes from Ireland's Heritage (Kyle Books; 2012).
Note: Colcannon may be prepared ahead and reheated later in a moderate oven at 350°F, for about 20-25 minutes. Any leftover colcannon may be formed into potato cakes and fried in bacon fat until crisp and brown on both sides—a cousin of bubble and squeak.
