Slideshow: Mashed Potatoes
- 3 pounds baking potatoes, peeled and cut into 2-inch pieces
- Fine sea salt
- 1 stick unsalted butter
- 1 1/4 cups buttermilk
- 1 teaspoon baking soda
- Freshly ground pepper
- Chopped chives, for garnish
- In a medium saucepan, cover the potatoes with 2 inches of water. Add 1 teaspoon of sea salt and bring to a boil, then simmer over moderate heat until the potatoes are tender when pierced, about 30 minutes. Drain well, then return the potatoes to the hot saucepan and mash with a potato masher.
- Meanwhile, in a small saucepan, melt the butter. Remove from the heat and stir in the buttermilk and baking soda; the mixture will foam up. Stir the buttermilk mixture into the mashed potatoes and season with sea salt and pepper. Scrape the potatoes into a serving bowl and garnish with chives. Serve warm.
Make AheadThe potatoes can be refrigerated overnight. Reheat before serving.
