Oldest food processor - crushing!



One method of processing fiber developed in the Stone Age, is crushing plants between two stones.  We use the mortar and pestle shown here.


Our initial use was specifically for making pesto using basil, garlic, walnuts, nutritional yeast, and sea salt.  However, now its use has expanded to make a variety of pestos. 


We have a 3+ cup capacity 8-inch diameter stone from a single block of granite.  It is practically indestructible – will not chip or crack even under vigorous pounding (Mohs scale 7+).  It’s also rather beautiful.  Cost was $34 online on Amazon.
