Colcannon is a traditional Irish side dish made with creamy mashed potatoes blended with sautéed cabbage and scallions.
2 pounds potatoes peeled and chopped
3 cups finely shredded green cabbage or chopped kale
4 tablespoons unsalted butter divided
1/2 cup whole milk warmed
3 scallions thinly sliced
Salt to taste
Black pepper to taste
Warm the milk before adding to keep potatoes hot and smooth. Avoid overmixing for best texture.
