Method
- Put the potatoes, 3 quarts cold water (adding more if needed to cover by 1 inch), and 2 teaspoons of the salt in an 8-quart pot.
- Bring to a boil over high heat.
- Adjust the heat to maintain a steady boil and cook for 15 to 20 minutes, until the potatoes are very tender when pierced with a fork.
- Drain the potatoes well and return them to the pot.
- Let them stand for 1 minute to release excess steam.
- Add the butter and mash the potatoes with a potato masher until the butter is melted and incorporated.
- Add the warm milk, sour cream, remaining 1 teaspoon salt, and pepper; mash until creamy, then serve hot.
Notes
For the creamiest texture, mash the potatoes while hot and avoid overworking them. Refrigerate leftovers in an airtight container for up to 4 days; freezing is not recommended because the texture may become grainy. For a lactose-free option, use dairy-free butter, milk, and sour cream.
