Place the potatoes in cold water before bringing to a boil so they cook evenly. Salt the water. The potatoes will absorb the flavor while boiling.
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.
“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.
For most potato dishes it's important to add the potatoes to cold water and allow the water to come to a boil with the potatoes in the water. The potato starch can react as soon as it comes in contact with hot water, which will promote uneven cooking and mealy potatoes.
When you boil potatoes, vegetables, pasta, etc. they absorb the flavor the liquid. So adding salt and vinegar to the water allows potatoes to absorb those flavors while boiling.
The other way is to increase the acidity of how you're cooking it. "Vinegar is an inherently acidic material, so if we add a few drops of vinegar into that boiling water that is going to increase the rate of denaturing and it's going to make that happen faster and help the poached egg hold its shape better."
Combine potatoes, 1 cup vinegar, and 1 Tbsp. kosher salt in a medium saucepan; add water to cover by 1”. Bring to a boil, reduce heat, and simmer until potatoes are tender, 20–25 minutes; drain and pat dry.
The most important part here is that you use cold water instead of boiled – if you boil the water first, the outside will cook faster than the inside resulting in an uneven texture. Cubed spuds will take around 15 minutes where larger chunks or whole new potatoes will be 20-25 minutes.
Bring the water to a boil. Reduce heat to medium low. 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.
Bring the potatoes to a boil, then generously salt the water. Reduce the heat if necessary to keep the pot at a gentle boil.
"Salt your potatoes at the end of the cooking process - not the start," they wrote on the post. This is because salt draws moisture from the inside of the potato to the surface - and nobody likes a soggy roast spud. Following these steps will give a "delicious glass-like crunch" they promise.
Follow this tip: Begin the process of seasoning your mashed potatoes by adding salt to the water when cooking the potatoes. You won't have to add as much salt later and, most importantly, you won't find yourself with bland potatoes.
Ideally, you should wait until your water is at a rolling boil. The boiling water will agitate and dissolve the salt quickly. You can add salt to your cold water if your prefer, though. You don't want to forget it after all!
Season with a teaspoon of salt per pound of potatoes. Bring water to a boil over high heat, then reduce heat to medium and cook at rapid simmer until potatoes are easily pierced with a paring knife, about 10 minutes for chopped potatoes and 20 minutes for whole potatoes.
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 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.
The experts at the Idaho Potato Commission — people who know their potatoes — recommend boiling potatoes with the skin on. This keeps the nutrients inside the potato during the cooking process and adds a bit of flavor and texture to the finished product as well.
Boil 10 to 12 minutes for cubed, 15 to 20 for whole medium-sized, or 25 to 30 for whole russets. Check with a fork or knife.
Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.
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).
Cold water boils faster than hot water.
There is, however, a good reason to use cold water instead of hot for cooking: hot water will contain more dissolved minerals from your pipes, which can give your food an off-flavor, particularly if you reduce the water a lot.
You can expect higher concentrations of acetic acid to increase the boiling point even more. Diluting the vinegar will bring the boiling point closer to that of pure water.
Boiling the potatoes in a salt and vinegar bath allows them to soak up all of that briny flavor before you dry them off and crisp them up in the oven. The result is a soft-in-the-center, crispy-on-the-outside potato that's loaded with flavor.
"Baking soda [what Americans call bicarbonate of soda] breaks down the pectin in the potato and draws starch to the surface. What do you get? Wonderful browning and a crispiness you wouldn't otherwise achieve.”
