Why does consuming the Francesinha necessarily require cutlery?

Answer

Due to its density, melted cheese, and abundant sauce

The structure of the Francesinha necessitates a sit-down approach using utensils, specifically a knife and fork. This is required because the sandwich is an architectural undertaking involving multiple layers of protein and bread, subsequently topped with melted cheese, creating a heavy structure. Crucially, the entire edifice is drenched in a heavy application of sauce until it is swimming, making any attempt to handle it manually an extremely messy endeavor that risks losing vital components, forcing the diner to eat it methodically.
