The "Sog Factor" remains the primary engineering challenge. A thin-cut fry (the Pommes Frites style) often fails under the duress of thermal regulation, becoming limp within moments of application. Conversely, the steak fry or the crinkle-cut provides necessary ridges and density. These "load-bearing walls" trap the cheese sauce, creating a perfect ratio of starch to dairy in every mouthful. The initial salting of the fry is paramount; it provides the essential savory contrast that cuts through the richness of the cheese, creating a flavor profile that is rounded and complete.
