Me three, but another way to do it, if you don't have time to roast a bulb of garlic is to gently
simmer whole garlic cloves in a small saucepan or skillet (make sure the garlic is covered with the oil) until the garlic softens. Takes less time than roasting garlic, and in my opinion, provides a better flavor than adding fresh garlic cloves to the boiling potatoes. And as a bonus, you'll have some garlic-flavored olive oil for other uses, like for pizza, vinaigrettes, sauteeing, etc.
