Instructions
Peel and cube the potatoes into 1-inch cubes. Place the potatoes into a large stock pan and cover them with cold tap water. Salt the water with 1 tablespoon of kosher salt.
Over high heat, bring the potatoes to a rapid boil, then reduce the heat to medium. Simmer until the potatoes are fork-tender (the chunks should fall apart easily when pieced with a fork.) This will take between 15-20 minutes.
Drain the potatoes in a large colander and then return to the hot pan. Place over low heat and simmer until all the moisture has evaporated–about 1-2 minutes.
Run potatoes through a ricer or mash using a handheld potato masher until potatoes are smooth.
Heat ¾ cup milk or cream and 3 tablespoons unsalted butter together in a small saucepan over low heat or in a glass measuring cup in the microwave, until the butter is melted. Slowly fold this mixture into the mashed potatoes, until it is fully absorbed and the potatoes are creamy.
Fold in ½ teaspoon kosher salt and ½ cup sour cream. Taste and adjust seasonings as needed. Serve with additional butter if desired.

Notes
Potatoes: I prefer Yukon Gold potatoes, for their natural buttery flavor and silky texture. But Russet potatoes work. Avoid waxy red or white potatoes. Milk/Cream: Use half and half, cream, whole milk, or low fat milk. Keep in mind for rich, restaurant-style mashed potatoes, cream or half and half is best. Serving Size: As a side dish, you should plan on ½ pound of potatoes per person. That means if you are planning on 10 people, use 5 pounds of potatoes. 4 people, use 2 pounds of potatoes.Hold Warm: Place potatoes into a large heat-safe bowl and place over a pot of simmering water (a makeshift double boiler). Cover loosely and stir every so often. They will stay perfectly warm and creamy for up to 1 hour.Storage: Refrigerate leftover mashed potatoes in an airtight container for up to 4 days, or freeze in a freezer-safe bag for up to 2 months. Reheat defrosted mashed potatoes in a covered casserole dish at 350°F until warmed through, adding a splash of milk to bring back that creamy texture.
