I'm looking at buying a pestle & mortar(molcajete) for making tamales.
The lady teaching this to my daughter says to be very careful when
purchasing as some are very low quality & get very gritty in the
grinding process. She emphasized that only a Mexican made one is high
enough quality to bother with. I am looking at a couple on

Any suggestions from familiar with these items? Which is the more
"authentic" the smoother or the rougher one? Or is this a non-issue?
Or can one of you guys make a recommendation on where to to buy one.
TIA
