The process of grinding and milling has its origins in prehistoric times, when early humans pounded grains and nuts with stones to free the kernel from the hard protective shell. The earliest dedicated tools for this task are the mortar and pestle, which were developed during the Stone Age and have remained essentially unchanged throughout history.
