Why Do French Fries Brown At The Surface Not In The Center?

Some of the starch in potatoes may be converted into sugars if the temperature is kept below 40 degrees Fahrenheit. If you fried these potatoes, the increased sugar content will cause them to brown too quickly, far before they are fully cooked in the middle. The sugars in the potatoes can be converted back into starch if they are kept for a few days in a warmer environment than normal.

Why do French fries burst when cooked in water?

In order to achieve the ideal texture for french fries, we must first allow the starches in the potatoes to gelatinize.

This process is known as starch hydrolysis.
