Basalt Stone Molcajete

A Molcajete is used to crush and grind spices, and to prepare salsas and guacamole. The rough surface of the basalt stone creates a superb grinding surface that maintains itself over time as tiny bubbles in the basalt are ground down, replenishing the textured surface.

A new basalt molcajete needs to be “broken in” because small grains of basalt can be loosened from the surface when it is first used and this will give an unpleasant gritty texture to the first few items prepared in it.
