Rinse twice to remove the starch: rinse once before cooking and one more time after cooking. Start with the potatoes in a pot of cold water (instead of pre-boiling the water) to ensure even cooking from the outside in.
Rinsing potatoes helps remove excess starch, so it is recommended to rinse the potatoes before cooking. To ensure even more starch is out of the way, it's recommended that they even be quickly rinsed after boiling. We recommend using hot water for rinsing after boiling and cold water prior to boiling.
For the fluffiest and lightest mashed potatoes, use Russets and rinse off excess potato starch before and after cooking.
Cover the pot with a lid and let simmer until fork-tender, about 10-15 minutes for small and/or cubed potatoes or 20-25 minutes for large potatoes. Drain and cool. Drain potatoes in a colander. To rapidly cool potatoes for recipes that call for cooled potatoes, you may submerge them in an ice bath.
Once you've got hot potatoes, you're almost ready to mash. Drain out any remaining water, add butter and milk and put the lid back on. The potatoes and warm pot will melt the butter and heat the milk. Let them sit for three to five minutes, then mash.
Tips for the Best Mashed Potatoes
Start cooking the potatoes in cold water: This ensures that the potatoes cook evenly. Otherwise, if you start with hot or boiling water, the outsides of the potatoes cook and soften while the middles are still hard and crunchy.
If keeping potatoes in water for more than an hour, refrigerate. However, don't soak them any longer than overnight—after that, the potatoes start to lose their structure and flavor.
Some people prefer to boil their potatoes whole, while others prefer to cut the vegetables into pieces before boiling. Smaller potatoes (like red gold) will cook faster whole—about 15-20 minutes in boiling water. Larger potatoes (like russet) take a little more time—about 20-30 minutes.
“Salting the water not only seasons the potato, but it also allows it to boil to a hotter temperature. This in turn cooks the potatoes' starch more thoroughly, resulting in a more creamy texture [for mashed potatoes],” says Sieger Bayer, Chef and Partner at The Heritage.
The Mistake: Overworking the Potatoes with a Food Processor, Blender or Mixer. Too much — or too vigorous — mashing will produce gluey potatoes. Your best tool is an old-fashioned masher, fork, ricer or food mill.
If kept warm, gently mash in heavy cream until smooth and loose again, adding more if you'd like. If cold, heat the cream in a large pot until steaming, then add the potatoes. Gently mash and whip, adding more cream as needed, until heated through and fluffy.
You shouldn't let butter be the only dairy you use, however. Consider adding half-and-half or heavy cream and a bit of sour cream (even goat cheese) to get the best flavor and creamiest texture every time, like in these Best Mashed Potatoes.
The Food and Drug Administration advises you wash potatoes before you eat them. Potatoes grow in the ground, and carry not only dirt but also bacteria to the grocery store and later, your table. Pesticides also remain on potato skin; even organic potatoes carry some degree of contaminants.
"In addition to good and bad bacterias, pesticides can linger in the soil and those need to go." According to the Centers for Disease Control and Prevention, at a minimum, potatoes should be rinsed with water before cutting for cooking.
Avoid getting specks of dirt in your spuds by thoroughly rinsing in cold water and scrubbing them first. If you throw cubed potatoes into a boiling pot of water, the outside will overcook and the inside won't cook enough.
If you find your mashed potatoes are soupier than normal, it's likely because you overcooked them, Buzzfeed says. Overcooked potatoes aren't always dry and hard, as it's possible to overboil a potato too.
The problem with overcooked potatoes is that they absorb a ton of water. When you go to mash them, they'll be soupy and sad. One way to fix them is by placing them in a pot over low heat and gently cooking them. The excess water will turn into steam, and your mash will dry out.
Put the cut potatoes in a large pot.
Add salt to the water, if desired. Bring the water to a boil over high heat, then reduce heat to medium low.
When potatoes are mashed, starch is released. The more you work the potatoes, the more starch gets released. When too much starch gets released, the potatoes become gummy, gluey, and unappetizing.
How long can peeled and cut potatoes sit in water before cooking, before they begin taking on too much water? A: We usually recommend no more than 24 hours. You can keep the potatoes from absorbing the water by making sure the water is not salted, and is chilled (you can even add ice to the water).
You'll need 454 grams (one pound), or roughly three medium potatoes, to yield four servings of mashed potatoes.
Do not add cold milk or cream to the pot of piping hot potatoes. Not only will this cool the dish down, but the cold liquid will not absorb into the hot potatoes very well. Warm the liquid in a saucepan on the stovetop or in a glass measuring cup in the microwave.
Swap Out the Water
In fact, when you mix the potato flakes with the warm broth, the result is a creamier, more buttery-tasting bowl of spuds. You can also swap milk or half-and-half for the water required.
Heavy cream will make for the creamiest mashed potatoes, but whole milk or half and half will also work. Don't use anything with less fat than whole milk, otherwise, your potatoes won't be as flavorful or creamy.
