Buy your best new potatoes — fingerlings if available, or like I did, new Maine Yukon Gold (in later April). This is an excellent accompaniment to a highly-flavored meat roast (like pork shoulder with garlic and rosemary). Very handy technique for a dinner party since it does its thing pretty much on its own while you cook other parts of the dinner or chat with your friends. When done, you can cover the pot and hold them for a bit.
Scrub and place taters in big pot with water to cover by an inch or more. Cut in half or more if large. Add salt. Bring to boil and cook uncovered until barely tender.
Drain most of the water from pot, leaving 1/2 inch or more. Add several cloves of garlic and slices of butter. Cook uncovered, stirring occasionally until water evaporates.
