Cutting the potatoes into small pieces. Just keep the chunks about 1 1/2 inches thick; if you cut them smaller, Foster says, they'll take in too much water, start to look transparent and won't soak up the other ingredients later. As you cut the potatoes, place them into a pot with cold water, so they don't discolor.
Do You Cut Potatoes Before Boiling? You don't have to cut potatoes to boil them, but smaller pieces of potato will boil faster than larger pieces. It will also be easier to work with smaller pieces if they will later become mashed potatoes.
Cut the potatoes into similar-sized chunks so they will cook evenly: the cubes should be about 1½ to two inches wide. 4. Put the cut potatoes in a large pot. Use a pot large enough to hold the potatoes with enough water to cover, plus room for the water to boil up without boiling over.
If you're here, you'll probably be glad to know that yes, you can peel and cut potatoes the day before you plan to serve them — and that it's super easy! All you have to do is submerge the bare potato pieces in water and refrigerate (more on that later).
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.
Regardless of what you've chosen to do with the peel, your potatoes will cook more quickly if you cut them up into chunks before boiling. They don't have to be super small, especially if you are going to be mashing them, but know that the smaller you cut the potatoes, the faster they will cook.
The Mistake: Cutting Potatoes Into Too-Small Pieces
They'll absorb too much water during cooking, preventing them from soaking up all the yummy butter and cream when it comes time for mashing. The best-size chunks for boiling: about 1 1/2 inches.
Don't soak cut potatoes longer than overnight.
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.
Potatoes can be peeled prepped and cut into water up to 2 days before boiling for mash.
Cutting the potatoes into small pieces.
Just keep the chunks about 1 1/2 inches thick; if you cut them smaller, Foster says, they'll take in too much water, start to look transparent and won't soak up the other ingredients later. As you cut the potatoes, place them into a pot with cold water, so they don't discolor.
Turn heat to high and cover slightly. Once boiling uncover and drop heat to a simmer. Cook until you can pierce potatoes easily with a fork, about 15 minutes. Strain potatoes and place back into the pot.
Turn the burner on high and bring water to boiling. Reduce the heat to medium-low or low. Cover the pot with a lid. Cook the potatoes in gently boiling water until tender, about 15 minutes for small red potatoes, new potatoes or cubed large russet potatoes, and 20 to 25 minutes for quartered potatoes.
Cut unpeeled potatoes into large chunks that are as even in size as possible. Place potato chunks into a pot of cold, salted water, cover, and bring to a boil. Boil the potatoes until they're tender, about 20 minutes. Thoroughly drain potatoes in a strainer and place back in the warm pot over low heat.
“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 lesson here is that you can keep potatoes from turning brown by storing cut potatoes in cold water to slow the oxidation process (aka the thing that makes peeled potatoes turn brown). You probably should keep them covered in an airtight container though.
You'll need 454 grams (one pound), or roughly three medium potatoes, to yield four servings of mashed potatoes.
The ideal temperature to keep mash potatoes warm is 300 degrees Fahrenheit, especially when you're using an oven or crock pot. But, to keep it warm without overcooking, make sure to put it in a pan or bowl covered with foil before placing it inside the oven.
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.
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.
The yolk emulsifies water and fat to create a cohesive, velvety bite, while providing a little fat and body of its own. What is this? You can add an egg yolk to nearly any existing mashed potato recipe.
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.
A word about butter: Don't melt butter before stirring it into the potatoes because the milk solids and fat will separate. You can add cold butter to your hot potatoes since the butter will melt as a whole and distribute the fat and milk solids evenly.
Here's how to do it: For every pound of potatoes in your mash, drizzle 1 tablespoon of melted butter over the dish and fold it gently into the potatoes. If the mash is still too gluey for your liking, repeat the process with another tablespoon of butter.
If your potatoes have been growing in very dry soil, the potatoes themselves will have a fairly low moisture content when harvested. What this then means is that when the potatoes are build they absorb more water and fall to pieces quite quickly.
