We demoed this in March — actually the day before St. Patrick’s Day, so totally appropriate for a uniquely Irish dish. And still appropriate by the way. When is mashed potatoes not appropriate? Because we were doing a series on radishes, turnips and potatoes, we used the turnip and radish greens in the colcannon. Man, was that a hit! Something about the slight bitterness in the greens with the sweetness of potatoes — I love Yukons, in case you hadn’t heard that before. Don’t over mash any of this — potatoes or greens. A little chunkiness goes a long way.
2 to 2½ pounds potatoes of your choice, peeled and cut into large chunks
5-6 T butter (with more butter for serving)
3 lightly packed cups of chopped kale, cabbage, chard, or other leafy green
1 bunch green onions (including the green onion greens), minced (about 1 C)
1/4 C milk or cream
Put the potatoes in a medium pot and cover with cold water by at least an inch. Add 2 tablespoons of salt, and bring to a boil. Boil gently until fork tender (15 to 20 minutes). Remove potatoes to a colander, reserving the potato water. Bring potato water back to a boil and add greens; reduce to a simmer and cook 3 min. Pour into a sieve, reserving the water for another use as needed. Return pan to heat. Add butter, 3/4 C green onions and cooked greens; simmer gently about three mins until onions are wilted and most of the water has cooked off. Add the potatoes back in; mash with a fork or masher, mixing well with the greens. Add milk or cream until you have the right consistency (may not use the full cup). Add salt and pepper to taste. Serve colcannon with a knob of butter in the center. Serves 4-6.
