(See previous post for Smothered Pork Chops for a picture of these potatoes.)
I wanted to serve the Smothered Pork Chops with potatoes of some sort and I had leftover buttermilk on hand. Did a quick Google search and voila! A recipe for Buttermilk Mashed Potatoes on Epicurious. They were absolutely delicious. I actually ended up throwing away half my pork chop but chowing down on these potatoes. The buttermilk gives them such a creamy texture without adding all the fat and calories of whole milk, cream, or sour cream. Plus, it gives them an interesting tangy flavor similar to what sour cream would. I will definitely make these again.
Buttermilk Mashed Potatoes
1 1/4 pounds thin-skinned potatoes, such as Yellow Finns or Yukon Golds, peeled and cut into 2-inch chunks if large
1 1/2 teaspoons kosher salt
3/4 cup buttermilk, warmed (not hot)
1 tablespoon unsalted butter
Freshly ground black pepper
Place the potatoes and 1 teaspoon of the salt in a medium saucepan, add enough water to cover, and bring to a boil over high heat. Reduce the heat to moderate and simmer until the potatoes are tender when pierced with a fork,about 45 minutes. Drain, reserving 1/4 cup of the cooking water.
Return the potatoes to the pan and set over low heat, uncovered, for about 5 minutes, stirring occasionally, to let the potatoes dry out a little (too much moisture will dilute their flavor). For the smoothest potatoes, pass them through a food mill. For a slightly coarser puree, mash them with a potato masher or fork or use a hand mixer. Beat the buttermilk into the potatoes with a wooden spoon until thoroughly incorporated. If you prefer even creamier potatoes, add a little of the reserved cooking liquid. Beat in the butter, the remaining 1/2 teaspoon salt, and plenty of pepper. Serve at once, or keep the potatoes warm, covered, in a double boiler over hot water for up to 1 hour.
In Advance: You can make the potatoes up to 3 hours ahead. About 20 minutes before serving, warm them in a double boiler, stirring frequently, until hot.
