What determines the flavor of Yesterday's soup?

The flavor of Yesterday's soup is primarily determined by the chef's daily choice. This reflects the culinary practice where chefs often create daily specials based on their creativity and inspiration, allowing them to experiment with various flavors, techniques, and ingredients. This allows for a dynamic menu that can change frequently, ensuring that the soup incorporates the chef's unique style and perspective, as well as their current preferences for flavors.

In this context, while customer orders can influence what gets made, they do not dictate the specific flavor profile of the soup. Seasonal ingredients play a role in determining the availability of certain flavors, yet it's the chef’s choice that ultimately dictates how those ingredients are used in creating the soup for a particular day. Lastly, a weekly menu can provide a framework for what to expect, but the specific flavors on any given day hinge on the chef’s decision.
