What constitutes extra mayo?

The concept of "extra mayo" typically implies an amount that surpasses the standard serving. In the context of Jimmy John's, the term generally indicates a significant increase in the quantity of mayo beyond what is considered a standard amount for a sandwich.

Choosing two heaping portions suggests a more generous application of mayo, aligning with the idea of providing an extra helping, as it visibly exceeds what is ordinarily expected. This distinction is important in culinary practices, especially in sandwich preparation, where the consistency of condiments can greatly affect the overall flavor and experience of the meal.

Other options, such as one heaping portion or a level portion, do not convey the same sense of an increased quantity sufficient to classify as "extra." The option describing a dash of mayo is also too minimal to fit the criteria for being labeled as extra, as it implies a very small amount rather than a noticeable increase. Thus, two heaping portions accurately reflect the desired modification when requesting extra mayo.
