Could a local ingredient be expensive because everyone knows when it is best?
Shared knowledge can concentrate demand.
Local food knowledge does not only help people buy better. It can also make buying more competitive.
The hidden mechanism is demand synchronization. If many shoppers, chefs, and vendors recognize the same short quality window, they all act at roughly the same time.
Imagine a regional fruit that tastes best for only a few weeks. Locals wait for that moment, restaurants build dishes around it, and market shoppers compete for the best supply.
A second-order effect develops because the ingredient's reputation strengthens each year. The more people learn the timing, the more concentrated demand becomes.
People often think seasonal prices rise because products are rare. Sometimes prices rise because knowledge is no longer rare.
