The soaking, Mr. Nasr said, is the secret to the crisp texture of the fries. It draws out the starch, making them more rigid and less likely to stick together. The cooks fry them twice, first blanching them until slightly limp in peanut oil heated to 325 degrees, and again in 375-degree oil to crisp and brown them.
Place them in a large bowl and cover with cold water. Allow them to soak, 2 to 3 hours. (You can also stick them in the fridge and let them soak overnight.) When you're ready to make the fries, drain off the water and lay the potatoes on 2 baking sheets lined with paper towels.
Soaking the sliced potatoes is the fundamental first step of making proper french fries. The soaking process removes the troublesome starch on the outside of the potato, which will help the fries achieve the perfect crispness.
Frying fresh-cut potatoes.
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.
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.
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.
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).
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.
Take a large bowl and soak the potatoes in cold water. Make sure that you soak the potatoes for at least 2-3 hours. Soaking the sliced potatoes in cold water is one of the main steps to prepare perfect French Fries. The cold water removes the starch present outside the potatoes so that you get perfectly crispy fries.
On that second fry, these straightened, simple pathways make it easier for water to escape, giving you a drier, crisper fry.
Fill a large bowl with cold water and stir in 2 tablespoons of salt. Place the sliced potatoes in the salt water and let them soak for 15 to 30 minutes. This will help them bake up crispier. When the potatoes are done soaking, drain them, and dry very well with a towel.
Here's what you do. Heat a few tablespoons of the oil in a nonstick pan over medium heat just until it starts to shimmer. Think about covering the entire bottom of the skillet in oil, erring on the side of using more oil than less. The oil helps to “fry” the French fries a second time and get them extra crispy.
The additional step of allowing the peeled, washed and cut potatoes to soak in cold water removes excess potato starch from the outside. This will help with the crisping up of the potatoes when they bake or roast. Soaking the potatoes in cold water also prevents the potatoes from browning too fast when cooking.
Why Soak the Potatoes in a Cold Brine? Soaking potatoes in cold water helps get rid of the starch, which makes them crispier. The sugar in the brine prevents them from soaking up too much oil when fried, which also makes them crisp.
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.
If you're using frozen French fries, you should know that there is no need to thaw these before frying. In fact, thawing can result in soggy fries. That's because the ice will melt and be soaked into the potatoes rather than immediately evaporating in the hot oil as soon as it hits it.
When to Season French Fries. Whether or not you season the french fries before or after they are cooked depends on the cooking method that you use: Deep Fried french fries are seasoned immediately after they're finished frying. Baked or Air Fried fries are seasoned before they're cooked.
Before all that, though, the secret is to briefly poach them in boiling water (or "blanch" them) before they go into the hot oil. This ensures that the fries are cooked all the way through before getting crisped up in the fryer.
Peanut oil or any light vegetable oil is necessary to make the best fried potatoes with the crispy crust you're looking for. I prefer peanut oil over olive oil because of its high smoke point but use what you have.
Give them a cold water bath: Once your potatoes are chopped, toss them into a large bowl. Then cover the potatoes completely with cold water and let them soak for at least 30 minutes (or up to overnight). This will help to rinse off the excess starch and help the potatoes crisp up beautifully in the oven.
Soak raw potatoes in a container for up to four hours. The potatoes should be fully submerged to prevent oxidation and discoloration. After four hours, the potatoes should be rinsed with cold water. Chopping, cutting or otherwise slicing the potatoes will excrete more starch.
What does soaking potatoes in water do? I soak sliced potatoes intended for fries in ice cubed, cold, slightly salted (kosher salt is the best) water, as it leeches out the excess starch and allows a better fry without as much starch.
What sets them apart from other crispy potatoes you might have encountered is the cooking process, which involves parboiling the potatoes before crisping them in a skillet. This allows for some of the starch to cook off, while also adding a big dose of flavor thanks to the salted water.
First, get the starch off! Rinsing or soaking the potatoes for an hour (or, even better, overnight) will remove some of the starch from the surface and prevent the sugars from browning before the potatoes are cooked.
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.
