An informal, unwritten list of dishes or culinary experiences, promoted through personal recommendations and social sharing, functions as a dynamic, evolving menu. For instance, a local bakery might not officially list its seasonal fruit tarts, yet loyal customers know to inquire about them based on previous positive encounters shared amongst friends and family.
This type of culinary communication builds trust and anticipation, often driving customer loyalty and discovery more effectively than traditional advertising. Historically, before widespread media, culinary traditions and local favorites were preserved and propagated through this informal channel, creating a sense of community and shared experience around food. This organic process continues to thrive today, amplified by digital platforms and social networks.
