Should you buy an ingredient that is famous but disappearing?
Popularity explains the past, not the future.
People often assume disappearing foods deserve to disappear.
That assumption is usually too simple.
The hidden mechanism is cultural evolution. Ingredients vanish for many reasons: convenience, economics, changing tastes, or industrial agriculture.
Sometimes the flavor remains excellent while the world around it changes.
People often think food history is a story of progress. It is also a story of forgotten favorites waiting for curious people to rediscover them.
