A type of hard candy, flavored with bergamot essence. According to the fine folks at the Tourism Lorraine website:
"Bergamotes, made using natural bergamot essence, were developed by accident. The woody tree was produced by a chance meeting between a wild orange tree and a lemon tree scion in Calabria during the Renaissance period."
Apparently, back in the day, citrus trees had not fully lost their Entish character, and were able to wander around Calabria at will.
