When Making French Fries At Home, Should I Cut The Strips Into Water With Salt Added? Is That Correct? (2024)

Back To Dr. Potato Home

Q:

I read this on the internet about making fresh cut fries at home using a two-step method: If you want to pre-soak the potatoes to get rid of starch, sometimes it's fun to dump a ton of salt into ice water to make them extra salty.

A:

The main reasons to cut the potatoes and pre-soak in water are: To allow the excess starches and sugars to be removed from the outer surface of the fry strips AND to keep the potatoes from browning prematurely from exposure to air. Covering in water helps the potato from turning a dark color. Adding salt to the water to form a brine mixture may seem helpful and can impart a flavor to the potato strips, however, salt is a major contributor to the fry oil breaking down prematurely, so I don’t recommend it. There is a restaurant out in San Francisco that soaks their potatoes in a water and vinegar solution, it adds flavor to the finished fries but this water/vinegar solution in enough to brine the potatoes isn’t salt free. While 1 teaspoon of vinegar may not have sodium show up in the Nutrition Facts chart, 2 tablespoons will have 1 mg of sodium. The two step method is designed to rid the potato strips of excess water, so they turn out extra crispy the second time they are fried in oil. A typical Idaho russet potato is about 20% solids or starch and 80% water. Cutting the potatoes, blanching in oil and then letting the potatoes rest and frying a second time makes for an extra crispy 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.

Why soaking potato strips in water and vinegar produces better fries? ›

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.

Why soak potatoes in water before frying? ›

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.

Why are my homemade fries not crispy? ›

If they are still not crispy you might have skipped a step or you might not have let them cool down sufficiently. Make sure to cool them in a single even layer and also make sure that the oil has the right temperature. Or maybe you've used the wrong potatoes to make them.

Why add vinegar in water for french fries? ›

When a small amount of vinegar is added to the soaking water before frying, it can help impart a tangy flavor to the fries without making them taste overly vinegary. The acid in the vinegar can also help to slightly break down the surface of the potatoes, aiding in the development of a crispier texture during frying.

What is the best oil for french fries? ›

Refined peanut oil is the best oil to use for making french fries. You can also use canola or safflower oil. Additionally, restaurant fries are so crispy because, among other things, they use old oil continuously.

Why do you fry fries twice? ›

Theory #1: "The first fry gets the outside to create a water tight barrier. That way, when you fry them the second time, they stay moist." Or, Theory #2: "The first fry cooks them through to the center—if you skipped that step, your fries would brown on the outside, but still be raw in the middle."

What happens if you don't soak potatoes before air frying? ›

I wouldn't bother doing potatoes from the raw state, without soaking. It will take about a half an hour and the texture won't be nearly as rewarding. They just don't get very crispy without that cold soak.

Can you soak potatoes too long? ›

When making thicker-cut fries, the potatoes shouldn't soak for more than 24 hours — or 12 if you're prepping super-thin shoestring fries. After too long, the potatoes may start to absorb water, which could result in mushy fries.

How long can I soak potatoes for fries? ›

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.

Should I salt potatoes before frying? ›

Before, after, or at the end? I will answer you right away: Salt can be added either in the oil, or the water in which the potatoes are soaked or at the end of cooking when we let them drain from the excess oil. However, the best option is to add salt in the water we soak them, as well as at the end of cooking.

Should you rinse starch off potatoes? ›

Rinsing potatoes helps remove excess starch, so it is recommended to rinse the potatoes before cooking. To ensure even more starch is out of the way, it's recommended that they even be quickly rinsed after boiling. We recommend using hot water for rinsing after boiling and cold water prior to boiling.

Should you salt french fries? ›

Unless a battered fry, they are not adding in salt during the process. I recommend not salting the fries till they come out of the fryer and even then, waiting for an order before salting as the fries can turn limp prematurely if salted too soon.

How do you get moisture out of french fries? ›

Blanching also works to reduce the moisture content of the French fry, helping them crisp up much more easily when fried. When the potatoes are transferred to the cold water after the hot liquid dip, the cells of the potato shrink, ensuring the fry will not absorb as much oil when it is later fried.
