Which of the following factors is least affected by food presentation?

The cooking method is the factor least affected by food presentation because it primarily involves the techniques and processes used to prepare food rather than how the food is arranged or displayed on the plate. While cooking methods can greatly influence the flavor, texture, and even aroma of a dish, they do not change based on how the food is presented to the diner.

In contrast, taste perception can indeed be influenced by the presentation of the food—how a dish looks can set expectations for its flavor. Visual appeal directly relates to presentation, as it encompasses the aesthetics of how a dish is plated. Finally, the overall meal experience incorporates taste, visual appeal, aroma, and even the ambiance of the dining setting, demonstrating a strong connection to food presentation in enhancing how a meal is enjoyed.
