Did you know that, once upon a time, salt was so valuable that it was used as currency? And, throughout history, salt wasn’t the only food used for that purpose.
In ancient Egypt, beer was used “as a currency to pay slaves, tradesmen, priests, and public officials”.
In the 1500’s in Tlaxcala (Mexico), three cacao beans could buy one turkey egg.
During the 1800’s, the Chinese bought opium with tea.
That’s herbed salt in the photo.
