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 the sliced potatoes in water helps to draw out some of the starch from the middle of the potato, resulting in a sturdier, crispier French fry.
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.
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. Blot with paper towels to dry them.
Soaking Potatoes
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.
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.
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.
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.
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.
(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.)
Potatoes will be firmer and crispier if you soak them in salt water before frying or cooking. Although it may seem like an extra step, this process will help you prepare the potatoes in advance.
They just won't stand up to an overnight soak, so don't do it. The larger the potato pieces, the longer they'll last in water. 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.
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.
Don't fry 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.
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.
Roasted potatoes can become soggy if the water content in the potato isn't fully cooked. Different potatoes have different water content percentages. Also, be mindful of the oil. Potatoes can react like sponges; too much oil can make your potatoes appear to be soggy.
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.
The presence of starch makes the texture of the potatoes soft and mushy, but at the same time it also adds on the carbohydrate content of potatoes. So, if you are planning to cut down on calories and enjoy your favourite potatoes without feeling guilty, then removing the starch content is the best thing to go for.
Soak the potatoes in enough cold water to cover, stir in 2 tablespoons vinegar and place in the fridge for at least 1 hour and up to 4 hours. When you refrigerate the potatoes, the starch will turn to sugar which is a good contrast to the vinegar in this recipe.
The foodie claims the trick to creamy and smooth mash to soak the skins in milk. Rob explains it's important to mix the skins of 'floury white-flesh potatoes' with milk in a saucepan over a high heat for two minutes – as this allows the flavour from the peel to infuse with the liquid.
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.
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.
To make crispy roast potatoes, the temperature of the oven needs to be hot 220°C or 425°F - but if the oven is too hot the potatoes will burn before they crisp up. If the oven temperature is too cold your potatoes will not be crispy.
soak your potatoes in room temperature water for 2 hours before you bake them. Yep! It really does make a difference. While resting in the water bath, the potatoes will soak up some of the water and this, in turn, will help make them fluffy inside when you bake them.
