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.
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). To keep the potatoes from turning black from oxidation, add 1 teaspoon of lemon juice or white wine vinegar to a gallon of water.
A: You can store peeled potatoes in water in the refrigerator for about 24 hours. Peeled potatoes left out by themselves at room temperature, on a refrigerator shelf or wrapped in foil or plastic wrap will still get dark overnight, so submerge them in a bowl of water, cover and refrigerate.
The reason is to prevent the potatoes exposure to air, which causes dehydration, oxidation, and discoloration. Immersing cut potatoes will also help rinse off excess starch.
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).
Remove the potatoes from the soaking water, place them in a towel and squeeze out as much moisture as possible. Allow the water to rest for about 30 minutes so the starch settles. Pour the water out of the bowl, leaving the starch at the bottom of the bowl. Combine the starch and potatoes just before cooking.
You can store the potatoes in water at room temperature for 1-2 hours. If you're not cooking the potatoes right away, you can keep safely store them in the fridge for up to 24 hours. For tips on handling discoloration in the water, read on!

If you're prepping with smaller pieces, don't soak for more than 12 hours. This trick is handy, but it'll only work for about 24 hours — so don't prep too far in advance. After too long they'll start to take on water and may lose their structure when you go to cook them.
You can prepare the spuds up to 24 hours before you need to cook with them. Then, on the evening you're planning to serve them, you can make creamy potatoes at the drop of the hat. Start by scrubbing potatoes under cool running water to remove dirt; dice, slice, or chop as directed in recipe.
Once the potatoes have soaked, rinse and drain them. Then — also very important — use a towel to pat them down until they are nice and dry before moving onto the next step. 3. Coat with cornstarch: Another next key to crispy potatoes?
In the presence of water, amylose molecules break down, whereas amylopectin molecules, another type of starch in potatoes, remain compact. So during washing and soaking, amylose is what we are removing. If excess amylose is not removed, the potatoes may be cooked unevenly.
If you want to get ahead, why not boil them in advance, then toss in a little oil and store in the fridge until you're ready to roast them. There's no need to bring them back up to room temperature, just toss them into hot fat straight from the fridge.
Soaking peeled, washed, and cut fries in cold water overnight removes excess potato starch, which prevents fries from sticking together and helps achieve maximum crispness.
Vinegar causes the potatoes to form a thin crust that further helps in retaining their shape. Vinegar increases the acid pH levels of water which further helps the potato just like when you add a little salt to the water while boiling eggs.
Doing so is a science thing – soaking cut potatoes removes excess potato starch. This means fluffy mashed potatoes (and not gluey!)
Yes, you should dry potatoes after soaking them in salt water for the right amount of time. Rinse and drain the whole potatoes or fries and pat them down with a towel until they are dry. Continue doing this process until you remove the excess moisture and the potatoes are ready to cook.
The result is very fluffy mashed potatoes. (If you decide to try soaking the raw potatoes anyway, they can be soaked in water in the refrigerator for several hours without any safety concerns. Potatoes can be soaked even overnight as long as they are in the refrigerator.)
SOAK your potato chunks in cold water.
This removes some of the starch and helps get them super duper crispy. Soak them at least one hour.
Why use salt water for soaking potatoes? There's moisture naturally found in potatoes, and moisture is drawn to higher concentrations of salt. (This is a process called osmosis.) So, if you put the potatoes in a salt water bath, that will help draw out some of their moisture, resulting in crispier fries.
Soaking raw potato slices in water for 15-30 minutes before frying or roasting helps reduce acrylamide formation during cooking. (Soaked potatoes should be drained and blotted dry before cooking to prevent splattering or fires.) Storing potatoes in the refrigerator can result in increased acrylamide during cooking.
Soak them in water
The best (and most popular) way to keep cut potatoes from turning brown is to completely submerge them in a bowl of water. Store the water-covered potatoes in a bowl in the refrigerator until you're ready to use them, up to one day in advance.
Potatoes can last for up to several months in a cool pantry. If stored at room temperature, they are best if eaten within one to two weeks. Once cooked, keep them in the fridge for no more than three days.
Raw potatoes that have been cut should be stored in a bowl of cold water and refrigerated. They'll be good for the next 24 hours. And finally, cooked potatoes will last three to four days in the fridge, as is the case with most leftovers.
Soak the uncooked potatoes for 30 minutes in an ice bath. They can soak longer, but you'll need to keep them in the fridge while they soak. Don't soak for longer than 3 hours.
