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.
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.
Chill the Potatoes
To get the perfect color, add a tablespoon of lemon juice and a few cups of ice to the water in which you have soaked the potatoes. Refrigerate the mixture for approximately 30 minutes. Chilling the potatoes will ensure that the potatoes don't turn brown too quickly.
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.
SOAK your potato chunks in cold water.
This removes some of the starch and helps get them super duper crispy.
Once it's time to cook with the potatoes, drain and rinse again with cold water. Washing the potatoes twice with water will remove excess starch, which will help them to get extra crispy when roasted or fried.
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.
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.
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.
Potatoes should never be stored on ice. The cold temperature will convert the starch into sugar, making the potatoes taste sweet. If stored this way the potato may actually freeze and break down when a consumer purchases these for home use.
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.
First of all, water within the potatoes evaporates, slightly drying out the potato. This is especially important if you're after a crispy crust. You will only get crispiness if enough water has left that outer part of your fry.
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.
Fries made from peeled potatoes should be chilled after cutting in cold water for 30 minutes to 2 hours before frying to ensure maximum crispiness.
If your homemade fried potatoes are soggy rather than the crispy potatoes you crave, or raw rather than tender, or even burnt rather than golden brown you are probably doing (or not doing) one of the following: You're using the wrong oil. You're using very starchy potatoes and not soaking to remove some of the starch.
It's best to parboil the potatoes first before pan frying to get cooked tender inside. In my experience, not boiling the potatoes first will result in not well cooked inside but crispy outer potatoes. Unless you are cutting the potatoes extra thin (which makes it like potatoes crips) then it's best to boil first.
Soak the potato strips in water with a dash of apple cider vinegar. Soaking the potatoes draws starch to the exterior of the potato. This prevents fries from sticking together and helps them get crispy. Vinegar delays potatoes from turning brown and also speeds up the starch extraction.
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.
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.
Rinsing or soaking cut raw potatoes helps to wash away a very small amount of amylose. But the potatoes must be cut into one-inch pieces to expose enough surface area to wash away any significant amount of amylose.
A: Chilling the water or adding ice is a method that helps the cells seal up and makes for a crisper fry when blanched. Warm or room temp water is better for leaching the starches, some operators or manufacturers actually blanch (or boil) the potatoes in water to remove excess starches.
The best potatoes for French fries are soaked in a sugar solution before frying. The sugar solution has something to do with the carbohydrates and prevents the potatoes from soaking up a lot of grease, so they get crunchy.
Air dry on paper towels; about 10 minutes. (Make sure the potatoes are dry before frying; you can dab them off with the paper towel if necessary.) Once potatoes are thoroughly dry, fry them 300-320 degree vegetable oil in a deep fryer or a large pot (a Dutch oven would work).
The trick to getting a perfectly crisp potato wedge is to soak the potatoes in an ice water bath for 30 minutes before baking them in the oven. This helps remove excess potato starch and make them extra crispy and delicious on the outside once cooked.
Dry the potatoes: It is important to dry your potatoes before frying them to prevent spattering. Use a clean towel to pat them dry on a sheet pan or put them into a salad dryer to remove the excess moisture. If you store the potatoes uncovered in your cooler overnight, this will help to further dry them out.
