Buttermilk-Chive Mashed Potatoes
Enriched with buttermilk and half-and-half, these mashed potatoes will turn out exceptionally smooth and fluffy if you use a potato ricer or a food mill.
- 5 lb. russet potatoes, peeled and cut into 2-inch pieces
- 2 tsp. kosher salt, plus more, to taste
- 3/4 cup buttermilk
- 1/2 cup half-and-half
- 8 Tbs. (1 stick) unsalted butter, cut into small pieces
- 3/4 cup finely chopped fresh chives
- Freshly ground white pepper, to taste
Put the potatoes in a large pot. Add the 2 tsp. salt and enough water to cover the potatoes by 3 inches. Bring to a boil over medium-high heat, reduce the heat to medium-low and simmer until the potatoes are tender when pierced, 15 to 20 minutes. Drain well in a colander.
In a small saucepan over medium heat, combine the buttermilk and half-and-half and heat until just warm. Set aside.
Set a potato ricer or food mill over the pot and pass the potatoes through in batches. Add the butter, then gradually add the buttermilk mixture, stirring constantly with a large wooden spoon until the potatoes are smooth and creamy. Stir in the chives and season with salt and white pepper. Transfer the potatoes to a warmed serving bowl and serve immediately. Serves 8 to 10.
