As with pasta water, there's a reason to liberally salt the water in which the potatoes will cook: As the starches in potatoes warm up, they open up and absorb water (and salt if you season the water).
But the most essential suggestion, per Bon Appétit, is always to salt the water you are boiling your mashed potatoes in. It acts as pre-seasoning, and Bon Appétit recommends adding a full cup of kosher salt to the boiling water.
As food writer and recipe developer Emma Laperruque explains at Food52, adding salt and vinegar to your mashed potatoes is a simple way to deepen and elevate your mashed potatoes without using expensive or hard-to-find ingredients.
Too much whipping (or mashing) will give you sticky — not fluffy — mashed potatoes. Make the best of it and turn them into cheesy mashed potato cups: Mix the potatoes with grated cheddar and an egg, then scoop the mixture into lightly greased muffin cups.
Add enough cold water to cover the tops of the potatoes. Add ½ to 1 teaspoon salt to the water. Turn the burner on high and bring water to boiling. Reduce the heat to medium-low or low.
The potato in the salt water shrinks because water moves from the potato into the more concentrated salt water. In contrast, water moves from the less concentrated distilled water into the potato causing it to expand.
If the salt concentration in the cup is higher than inside the potato cells, water moves out of the potato into the cup. This leads to shrinkage of the potato cells, which explains why the potato strips get smaller in length and diameter.
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. It's that easy!
Make sure the milk or cream you add to your potatoes is HOT. This helps it absorb better so you don't feel the need to overmix.
If you find your potatoes are too salty, adding more liquid, such as milk or buttermilk, or more potatoes can help tone it down. No more potatoes on hand? Try adding some mashed cauliflower or root vegetables to the mix.
Salting the water before you add the pasta is the best way to get evenly seasoned noodles. And you should wait until the water is actually boiling. This not only helps the salt dissolve faster, but it also protects your pot.
Cover the potatoes with water and season with 1 teaspoon of the salt. Boil the potatoes until they are fork tender. Drain the potatoes and return them to the saucepan. Add 1/2 cup of the butter, hot milk, sour cream, and salt to taste; mash thoroughly with a potato masher until very creamy.
No. You don't need to soak potatoes before making them into mashed potatoes.
Dissolve the salt in a large bowl filled with warm water. Wash but do not put holes in the potatoes. Add potatoes to the salt water so they are completely submerged. Soak for a minimum of 2 hours.
It Gives a Firmer Texture
Since soaking potatoes in salt water draws out excess moisture and reduces their ability to absorb oil, it helps them have a firmer texture.
Restaurants prepare the potatoes ahead by boiling and mashing just the potato, then just before serving, it is mixed into boiling cream (or milk or even broth or a combination thereof) to reheat it and make it nice and creamy.
Warm the milk in a small saucepan before incorporating it into your mash. When you melt butter on the stove, its milk solids and fat separate. Adding cold butter to your potatoes will allow the butter to melt as a whole and distribute the fat and milk solids evenly.
To avoid this, all you have to do is add the butter first, because it will coat the starch in fat to shield it from the water in the cream, and as a result, you'll end up with silky mashed potatoes rather than gluey ones.
Potatoes that have been beaten too much turn into a sticky, gooey paste because the starch in potatoes has been released. You also may have overcooked them (can you see how sensitive potatoes are?). Overcooking them makes them extra-soft and extra-easy to overbeat, again making them rubbery.
This process, which is called oxidation, happens because potatoes are a naturally starchy vegetable. And when exposed to oxygen, starches turn gray, brown, or even black. An oxidized potato is completely safe to eat. The process doesn't affect the flavor or texture of the vegetable.
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.
Yes, salt helps cook potatoes faster. Salt water boils faster than plain water. The reason is that salt makes the water denser (or heavier). It takes up more space per unit of volume, so it takes less time to get to the boiling point.
As the amount of sugar solution increases in the other containers, the mass of the potato cores goes down. If the water is highly concentrated with sugar, the water actually leaves the potato because there is a higher concentration of pure water in the potato than there is in the sugar water.
According to Bon Appétit, extremely salty water makes the best boiled potatoes. Why? Potatoes without seasoning are bland and flavorless, and salt adds delicious flavor. Potatoes are dense and require time to absorb some of the salt during cooking.
