I recently found out from a friend that the black olives that you often see (EG: at subway) are dyed black and are infact green olives! 🫒🤢 There are some naturally black olives, however it is only when they are very mature or they have a glaucescent (whitish powder) like surface and are very clearly different! Olive turn from green to blackish as they mature and soften. Often the tastiest olives are those brownish ones that look a bit old, so soft and juicy though 😮💨 What's your favourite olive?
