MASHED POTATOES WITH MILK AND SOUR CREAM RECIPES

Steps:

• Cut the potatoes into 1-inch cubes and place them in a large pot. Cover the potatoes with cold water and add enough salt so the water tastes quite salty. Bring to a boil, then lower the heat and simmer, uncovered, for about 10 to 12 minutes, until the potatoes fall apart easily when pierced with a fork.
• Meanwhile, heat the milk and butter in a small saucepan, making sure it doesn't boil. Set aside until the potatoes are done.
• As soon as the potatoes are tender, drain them in a colander. Place a food mill fitted with a small disc/blade over a glass bowl. Process the potatoes through the food mill, turning the handle back and forth to force the potatoes through the disc. As soon as the potatoes are mashed, slowly whisk in enough of the hot milk/butter mixture to make the potatoes very creamy. Add 2 teaspoons of salt and the sour cream and pepper and whisk to combine. Taste for seasoning and serve hot.

Steps:

• Cover potatoes, garlic, and 1 Tbsp. salt with cold water in a large pot. Bring to a low boil, then reduce heat and simmer (do not boil) until potatoes are very tender when pierced with the tip of a paring knife but not falling apart, 20–25 minutes.
• Meanwhile, heat milk, thyme, and ¾ cup butter in a small pot over medium, stirring, until butter is melted. Remove from heat; set aside.
• Drain potatoes and garlic; return to pot. Toss over low heat until moisture evaporates, 1–2 minutes. Using potato ricer or food mill, immediately press potatoes and garlic into a large bowl (do not let cool).
• Discard thyme from milk mixture and gradually stir into potatoes, reserving about ½ cup if you plan to make in advance (see Do Ahead). Season with 2 tsp. salt and ¾ tsp. pepper. Fold in sour cream and stir with a spoon until incorporated and very smooth (do not overmix or potatoes will become gummy). Taste and adjust seasonings. Serve topped with remaining 2 Tbsp. butter and more pepper.
• Mashed potatoes can be made 2 hours ahead; cover and store at room temperature. Or chill, covered, up to 8 hours; reheat over medium with reserved ½ cup milk mixture.
