The molcajete is a traditional Mesoamerican mortar and pestle, widely used in Mexico. It is used to grind or crush foods, such as grains, spices, and vegetables, intended for the preparation of sauces and other dishes. To grind the ingredients, a stone cylinder called tejolote or commonly referred to as a molcajete stone is used. The molcajete should not be confused with the metate, which is used to grind corn.
