In ancient Mayan kitchens, a built-in blender station called a 'molcajete' was commonly used. The molcajete was made of volcanic stone and had a bowl-like shape. Mayans used this blender station to grind and blend ingredients like spices, herbs, and chilies. The molcajete played a crucial role in Mayan cuisine, allowing them to create rich and flavorful salsas, sauces, and marinades.
