Ammikallu is a Malayalam term that refers to traditional kitchen tool used in India  to ground spices. It is a stone grinder used in Kerala, India to grind spices extensively used for cooking foods. It is a flat, rectangular-shaped stone with cylindrical stone pestle.

It is not like an ordinary mortar and pestle where foods (spices/foods) are pounded. In Ammikallu , the spices and foods are put on top or the surface of the flat stone then grounded using the pestle until they turned into a thick paste.

Ammikallu is also spelled Ammi Kallu.
