Cooking steps
-
1
Peel and chop the potatoes into even chunks, then place them in a large pot with just enough water to cover. Add 1 teaspoon of salt. Bring to a boil, then reduce heat and simmer for 15–20 minutes until fork-tender.
-
2
While the potatoes cook, slice the cabbage thinly and chop the scallions. Melt 1/4 cup unsalted butter in a large skillet over medium heat, add the cabbage, and sauté for 8–10 minutes until softened but not browned.
-
3
Drain the cooked potatoes thoroughly and return them to the warm pot over low heat for 1–2 minutes to steam off excess moisture; this makes for creamier mash.
-
4
Mash the potatoes with a potato masher or ricer. Gradually add warmed milk and 1/4 cup butter, mixing until smooth and fluffy. Fold in the sautéed cabbage and sliced scallions until evenly combined.
-
5
Season with the remaining salt and black pepper to taste. Transfer the colcannon to a serving bowl and use a spoon to make a well in the center; fill with the remaining melted butter as tradition dictates before serving hot. Enjoy as part of your St. Patrick's Day menu and savor a true taste of Ireland!
