Rinse potatoes and cut into cubes (the larger the cube the longer it will take to cook so size is up to you)
Place cubed potatoes in a pan and completely cover with water.
Bring to a boil and allow to cook until fork tender.
Drain potatoes, place back in warm pan and cover with a towel for a few minutes.
Smash the potatoes with a fork or a hand potato masher adding milk till you reached your desired consistency.
