RSVP Endurance Authentic Mexican MolcajeteI had one before! My mother passed it down to me.. Some how it has been misplaced, I ordered this one & it's good to go!
My son-in-law had just been to Mexico and when he came back he wanted an authentic mortar and pestle for making salsa - just like the one he used while on vacation. Well, this fit the bill! He's very happy with it!
So apparently living on the US/Mexico border is no guarantee that you will find authentic basaltic rock molcajete just down the street. In fact, I asked a friend to look for one and ended up with a painted-over concrete molcajete that is perfect for putting some fake rice or beans in and sitting next to the bowl of plastic fruit.In any case, the molcajete and tejolote from TheLatinProducts is the real deal! Looks and feels solid, smells like rock, and arrived in some pretty stout packaging.
Bought for son and he has used it a few times. He had one larger but really likes this one. Price was good, shipping was fast and good packaging
I bought this as a gift for my friend because she makes great guacamole and I thought this would be great for presentation. The molcajete arrived and it seems to be made well. It is heavy and sturdy and actually bigger than I thought it would be. It is a steal for the price. William Sonoma has one for 49.99 and Kohls sells one for 69.99. You do have to season it before use and there are instructions on how to do that in the package.
I rarely write reviews, but this beauty deserves one. I wasn't sure from the description and comments what to expect in terms of size. So for those wondering, mine is 8&#34; in total diameter (7&#34; interior diameter), 4.5&#34; tall and holds 32 ozs of water! It's big and beautiful. I own a taqueria and bought one for the shop, I couldn't be more pleased. I will be ordering more.
The molcajete is vere authentic and very good appearance. The package was wrapped very good, but the shipping time was more than estimate.
We purchased this Molcajete after taking a cooking class in Mexico. It is a must have for making Petptas Salsa (Ha'Si-Kil). The molcajete is nice and heavy and does not move around the counter when used. Seasoning it was a breeze, following the instructions included in the shipment. I'd recommend this item to anyone who has attended Chef Claudia's class or just wants a large molcajete for making Guacamole and other salsas.
bought this for my wife and i had to season it. just grinding whith the pestal is for the birds. if you use a drill and wire brush, it helps smooth it out a lot. if you use a peanut grinder thats evan faster. i spent a hour or so with power tools and then used the rice to finish it out. i hope this helps someone other than me. fast delivery and a nice looking rock. thank you.
Answer: I purchased one and it feels pretty darned authentic to me.  I love it!  It is solid and quite heavy.  I spent about two days grinding brown rice (brown is not required, just my preference) into all the cracks and crevices.  It comes with clear instructions.  I also presoaked it in heavily salted water.
