How to cook mashed potatoes
Put the potatoes into a large pot of water.
Do not peel or cut the potatoes. Instead, scrub them clean first, then put them into a large pot.
Fill the pot enough water until the water level is 1 inch (2.54 centimeters) above the potatoes. Keeping the potatoes whole (not peeled or cut) will prevent them from absorbing too much water.
