A basic guideline for how I make mashed potatoes on the stovetop.
I can't imagine Thanksgiving without mashed potatoes, so I made a big batch for my family.
This is more or less the general method I use to make mashed potatoes - I chop up a bag of Yukon Gold (or Russet) potatoes and put them in a big pot, fill it with water, add a generous pinch of salt and boil until tender.
Drain and return to the hot pot. Drop in a few tablespoons of butter, a few generous splashes of milk, and a few big dollops of sour cream. Season well with salt and pepper and mash to your desired consistency.
Sometimes I add cream cheese, and sometimes I peel the potatoes - it's totally up to how rich you want them. If they're too thick, add more milk.
They're always great! I topped them with some of the gravy that my in-laws brought over, and it was perfect!
