Does Starch Make Fries Crispy?
Starch is a key ingredient in making fries crispy. When potatoes are cut and soaked in water, the starch granules on the surface of the potatoes are released. Coating the fries in cornstarch or flour before frying them helps to form a crispy outer layer by absorbing excess moisture and creating a crunchy texture. However, overdoing the amount of starch can lead to a heavy, doughy coating that can negatively affect the texture.
