Authentic Salsa
Sure, you can make salsa in any container with the help of a blender. But why sacrifice the rustic textures and flavors begot by making your salsa in an authentic basalt volcanic molcajete? Because the mortar is porous, it stores flavors (it's best to season a molcajete with garlic and leave it over night when you first get it) and imparts them to later bowl contents. Because the stone is rough, it gives salsas, moles, and guacamoles that distinct texture that has added that certain authentic quality for the past 5,000 years!
