Was surprised at the type of stone this was. I expected more of the negra coarse basalt. I have limited experience with molcajetes and was hoping for one like my last one. This one seems like it's closer to being some other kind of stone, than to the porous basalt I wanted. However I decided to keep it and give it a try. I ground up a pile of rice in it, washed it, ground in some garlic, lathered rinsed repeated. Then I proceeded to make some salsa a guacamole. It worked just fine and I didn't find any grit. I think it's a keeper, and it should work just fine. It's big enough that I can make decent sized batches.
