Since summer has just started and hot weather brings to mind ice cream and other cooling treats, I learned today that 4,000 years ago, Chinese people enjoyed a kind of frozen syrup. Centuries later, around 400 B.C., sharbat was a popular treat in the Persian Empire. This cold drink featured syrups made from cherries, quinces and pomegranates that were then cooled with snow. The modern words "sherbet," "sorbet" and "syrup" can trace their linguistic recipe origins back to sharbat.
