How Long Should You Soak Potatoes When Making Fries?
You may have heard home chefs suggest soaking your potatoes in water when making french fries. This step will ensure a crispy fry, and there’s a scientific reason.
Soaking the potatoes first removes excess acrylamide, a food starch. Although naturally occurring, too much of the starch makes the fries go limp.
You need to remove enough of the starch to get crispy fries. Per a study in Science of Food and Agriculture, soaking the cut potatoes for two hours lowers acrylamide levels by 48%.
If you are in a hurry, however, 30 minutes will still take out 38% of the acrylamide, while a simple cold water rinse removes 23% of the starch.
