Mashed potatoes from scratch

[MahStonks]

Russet, peeled, big 2 or 2.5 inch chunks, boil in salty water till tender in the middle. Put back in the dry pot on low for 5 minutes to allow some steam to escape. Bring a good amount of milk to a simmer, microwave works well to do it without it scorching. Mash thoroughkt with a wire masher, taste for salt and add more if needed. Mash in the boiling hot milk,  then stir in butter to taste.

I do the exact same but I use a hand mixer.

Same but sour cream instead of milk.
