Wash the potatoes, but do not peel.
Place the potatoes in a pot of salted water and bring to a boil. Reduce to low and simmer until fork tender.
Completely drain out all the water. Lay the potatoes out to dry for 5 minutes.
Slightly smash the potatoes with a meat tenderizier, a big spoon, or your hand. Just gently push down on them until they are flatten just a bit.
Cover a frying pan with enough oil or fat to cover the surface. Heat the pan up over medium high heat.
Add the potatoes without them touching, you'll have to work in batches. Cook until brown on one side and flip. About a couple minutes per side. You may need to add more oil or fat between batches.
Salt to taste and serve hot.
