This mortar is sturdy and heavy, polished on the outside, and matte within to add resistance, and enhance the grinding surface. The slim pestle, slightly wider at the base, is polished except for its grinding tip, which is matte to match the interior of the mortar. This mortar and pestle makes quick work of a cup of basil, garlic, and pine nuts for a pesto, as well as almonds, dried thyme, cardamom pods, and juniper berries. The marble stays cool while you work and is easy to clean afterwards. The mortar is 5.25 inches in diameter and stands 4.5 inches tall.
