A
mortar and pestle is a
tool used to crush, grind, and mix substances. The pestle is a heavy stick whose end is used for pounding and grinding, and the mortar is a bowl. The substance is ground between the pestle and the mortar.
The English "pestle" derives from classical Latin "pistillum", meaning "pounder". The classical Latin "mortarium" led to the English "mortar", meaning, among several other usages, "receptacle for pounding" and "product of grinding or pounding". The Roman poet Juvenal applied both "mortarium" and "pistillum" to articles used in the preparation of drugs, reflecting the early use of the mortar & pestle as a pharmacist's or apothecary's symbol as described below.[1] The antiquity of these tools is well documented in some early literature, such as the Egyptian "Papyrus Ebers" of c. 1550 B.C.E. (the oldest preserved medical literature piece) and the Old Testament (Numbers 118 and Proverbs 2722).[2]
Mortars and pestles were traditionally used in pharmacies to crush various ingredients prior to preparing an extemporaneous prescription. The mortar and pestle is the most common icon associated with pharmacies. For pharmaceutical use, the mortar and the head of the pestle are usually made of porcelain, while the handle of the pestle is made of wood. This is known as a Wedgwood mortar and pestle and originated in 1779. Today the act of mixing ingredients or reducing the particle size is known as trituration. Mortars and pestles are also used as drug paraphernalia in order to grind up pills to speed up absorption when they are ingested or in preparation for insufflation (snorting).
Mortars are also used in cooking to prepare ingredients such as guacamole and pesto (which derives its name from the pestle pounding), as well as grinding spices into powder. Native American tribes used mortars carved into the bedrock to grind acorns and other nuts. Many such depressions can be found in their former territories. Very large mortars are used with wooden mallets to prepare mochi. A regular sized Japanese mortar and pestle is called suribachi and surikogi. Granite mortars and pestles are used in Southeast Asia and India. In Malay, it is known as lesung. Traditional Mexican mortar and pestles, made of basalt, are known as molcajetes. Large stone mortars, with long (2-3 feet) wood pestles were also used in the Middle East to grind meat in order to prepare a type of meatloaf, or kibbeh, as well as the hummus variety known as masabcha.
