When fries are cooked at a very high temperature, the starches in them are hydrated (moisture goes in), puffing them up and helping the outer skin get nice and crisp. When these same fries cool, the starches secrete moisture, which makes its way to the fries’ crust, leaving them soggy and limp.
Q. Why do you fry French fries twice?
The famous Maillard reactions are turning them golden-brown. The secret around this problem is to fry your food twice. Moisture in the center of the food migrates to the surface after the food cools and the surface gets soggy again. Then you boil off that moisture again on the second fry.

Q. What happens when frying?
Any food cooked in hot fat is fried. When food is added to hot oil (usually 350°F to 375°F), its surface dehydrates. Meanwhile, through a series of Maillard reactions (named after the chemist Louis Camille Maillard), its sugars and proteins break down to create complex flavor and golden-brown color.
Q. Why are my fries not crispy?
You do need to have the cooking time for high-starch potatoes just right. If you cook them too long, they’ll run out of internal moisture. Without this moisture to turn to steam pushing outward, the fries become greasy.
Q. How do you know when French fries are done frying?
Leave the fried potatoes to cook thoroughly until they float to the top of the oil. Once they float up to the top and stay there for one full minute, they are done. The key to knowing when they are done is that they will all float and stay on the surface of the oil.
