A mortar and pestle is a traditional tool used for grinding and mixing substances. The mortar is a bowl, typically made of materials like wood, stone, or ceramic, while the pestle is a heavy, club-shaped object used to crush and grind the contents. This tool is commonly used in cooking to prepare spices, herbs, and pastes. In addition to culinary uses, the mortar and pestle are also employed in pharmacy and laboratories for grinding chemicals and compounds. The process allows for better extraction of flavors or active ingredients, making it a valuable tool in both kitchens and scientific settings.
