What signifies that a final fry is undercooked?

The indication that a final fry is undercooked is characterized by a raw taste and lighter color. When fries are not cooked thoroughly, they often maintain an underdone flavor due to the potato not being properly cooked through and integrated with the oils. Additionally, light coloration can suggest that the fries have not been subjected to sufficient cooking time or temperature, resulting in a less crispy texture that hasn't developed the rich golden-brown color associated with well-cooked fries.

In contrast, choices that reference darker color typically signal overcooking or burning, while overly crispy textures can indicate cooking beyond the ideal time. A soft and spongy consistency is often a sign of undercooking as well, but in this context, the raw taste combined with lighter color offers a clearer representation of undercooked fries.
