A molcajete is a stone mortar and pestle from Mexico. They're great for grinding spices and making salsa and guacamole because they give everything a nice coarse and rustic feel. I've never collected anything, but I think I might start collecting these because each one is decorated differently.
I think what's happening here is, there's a group or maybe one person who is saying this is gonna be the definition and this is what we want to get the kids to do now.
