This is my go to basic mashed potato recipe. It's perfect and fluffy each and every time.
Peel and cut the potatoes into even size chucks. Rinse the chunks and place them in stock pot. Cover with water and bring to a boil. Cook for 20-25 minutes until fork tender.
Drain the potatoes and return them to the pot. Return to pot to the stove top and reduce the temperature to medium heat. Using a potato masher, go a few times around the pot and break up the potatoes. This will allow them to release excess moisture. Turn heat off.
Add room temperature butter, hot milk, salt and pepper and continue to mash until you have fluffy mashed potatoes. Taste and reseason as necessary.
