What indicates that the fries are properly cooked during the final cook process?

Fries are considered properly cooked when they change color and float. During the cooking process, the oil heats up the fries, causing moisture to escape. As the fries reach the optimal temperature, they undergo a transformation in their physical properties.

The color change signifies that they are being cooked correctly and developing that desirable golden-brown exterior, which is a hallmark of well-prepared fries. Additionally, as the moisture dissipates and the fries cook, they become less dense, allowing them to float to the surface of the oil. This floating characteristic is an indication that they are nearing completion and have reached the right texture and doneness.

In contrast, fries that are dark in color may suggest overcooking, while fries that remain at the bottom of the basket are likely undercooked or too dense due to excess moisture. Lastly, fries absorbing more oil is not a desired sign; it typically indicates they are not cooked sufficiently, potentially resulting in a soggy texture rather than the crispy finish that is characteristic of well-prepared fries.
