Where does extra salt go on a burger?

The correct answer indicates that extra salt should be added on the tomato. This practice is based on culinary techniques that highlight the flavor of fresh produce. Adding salt to the tomato enhances its natural sweetness and brings out a more vibrant flavor profile, creating a better overall taste experience in the burger.

In contrast, while some might think to add salt to the patty, it's typically seasoned during cooking to avoid drawing moisture out, which can lead to a drier burger. Salt on the bun is not common, as it doesn't contribute much to the flavor and might create an undesirable texture. Lastly, putting salt in the wrapper would have no practical culinary benefit, as it wouldn't interact with the burger components effectively.
