Wash the potatoes.
Peel, cut, and rinse the potatoes. Place them in a large pot and fill with water to 1" above the potatoes. Add the peeled garlic cloves and salt.
Bring to a boil (uncovered), then turn the heat to medium and cook for 15 minutes or until the potatoes are fork tender.
Check the potatoes periodically for doneness.
While the potatoes are cooking, warm the milk in the microwave just to take the chill off.
Drain the potatoes in a colander or sieve being careful to avoid the steam billowing into your face and on your arms.
Leave the potatoes to drain for a couple minutes. Do not remove the garlic cloves or rinse the potatoes!
Meanwhile, put a tablespoon of butter in the bottom of the hot potato pot and let it melt.
