Colcannon is a traditional Irish recipe, typically made by incorporating cabbage or kale into mashed potatoes. It’s just about as easy as could be. First, peel the potatoes—the easiest way is to hold them vertically in the palm of you hand and peel away from you using a y-shaped peeler—quarter them and throw them in a pot to boil. We went with kale this time and it gets tossed right in the same water we used for the potatoes. Before you mash, be sure to squeeze out as much water as you can from the kale to prevent a watery batch.
