Mortar & Pestle
A kitchen tool that is used to grind, crush, and mash herbs, spices, and vegetables to make a paste, sauce or seasoning. The bowl shaped container is known as the mortar and the mini baseball bat shaped handheld tool is the pestle. The two pieces are generally made from the same material, usually porcelain, stoneware, wood, or marble. Traditional pesto sauce is made using one.
