Description: This spice grinder made of solid cast iron and beechwood is a durable and indestructible tool for grinding spices, peppers, herbs and more. The weight and strength of this cast iron grinder will break down spices to desired coarseness (more turns produce a finer grind). The inner cup's bottom ridges crush even the most obstinate seeds against the outer cup's walls. Leftover ground spices can be stored beneath the inner cup's lid. 3.3 x 3.5". Remove dry residues with a brush only. Rinse with hot water and a dishwashing brush to remove residues of acid or oil. Dry thoroughly. Do not immerse in water. Not dishwasher safe. Lubricate mortar occasionally.
