Which of the following is NOT a direct outcome of maintaining proper ingredient proportions?

Maintaining proper ingredient proportions plays a crucial role in various aspects of food preparation and service. When ingredients are balanced correctly, it leads to increased customer satisfaction because the flavor and quality of the food meet customer expectations. Additionally, proper proportions can contribute to higher food cost efficiency by minimizing waste and maximizing the use of ingredients, directly impacting the business's bottom line.

Consistency in food quality is another key outcome, as proper proportions ensure that each item meets the same standards each time it is prepared. This reliability fosters trust and loyalty among customers, who appreciate knowing that they will receive the same great taste with every order.

However, while maintaining ingredient proportions is essential for overall food quality and satisfaction, it does not directly influence customer wait times. Customer wait times are typically determined by factors such as kitchen efficiency, staff training, and the overall workflow of food preparation rather than the accuracy of ingredient measurements. Therefore, option C stands out as it is not a direct result of maintaining proper ingredient proportions.
