What is a fundamental aspect of the cooking process regarding salt at In-N-Out?

The correct answer indicates that salt should be sprinkled before cooking, which is a crucial aspect of enhancing the flavor of the food during the cooking process. Applying salt before cooking allows it to penetrate the meat and vegetables, ensuring a more even distribution of flavor throughout the dish. This technique is especially important in fast-food settings like In-N-Out, where efficiency and consistent taste are key.

Salting before cooking is based on the principle that salt can help in tenderizing the meat and drawing out moisture, which can enhance the overall taste and texture once the food is cooked. The timing of when to salt can significantly impact the final outcome of the dish.

Other answer choices illustrate different approaches to applying salt. However, they do not capture the essential pre-cooking aspect that ensures the flavors are locked in during the cooking process.
