Scrub the potatoes clean, remove skin, and cut them into large cubes.
Add the potatoes to a saucepan and cover them with two inches of cold water and make sure there is some room left on the tops. Add the salt into the water and stir until dissolved.
Bring the potatoes to a boil over medium-high heat, then reduce to a simmer. Place the pot over medium-high heat and bring to a boil.
The potatoes are ready when you poke a potato with a fork and it’s slides all the way to the centre. It is now tender.
Drain the potatoes in a strainer or with a slotted spoon.
In a bowl, mash the potatoes with the milk using a stand mixer or potato masher. Stir in sour cream, salt and pepper.
Sprinkle the creamy potatoes with green onions or chives, and add butter to taste.
Notes
For a lighter recipe, low-fat sour cream can be used.Can you make mashed potatoes ahead of time?Once the mashed potatoes are prepared (omit the butter and green onions or chives), you can put them into a large microwave-safe bowl and cover tightly with plastic wrap while leaving about an inch from the top. You can refrigerate for up to 2 days.
To reheat in the microwave, poke about 6 holes in the plastic wrap, and microwave at medium-high (70 percent) until the potatoes are hot (check after 10 minutes, and add by increments of 1 minute until you find them hot enough) and stir halfway through the reheating time. Sprinkle the creamy potatoes with green onions or chives and add butter.
To reheat on the stove top, remove the creamy potatoes from the bowl, and cook them in a saucepan over low heat. Stir frequently until they are hot. Sprinkle the creamy potatoes with green onions or chives and add butter.
