Molinito Sand (for Stones)

Molinito Sand (for Stones)


If you have begun breaking in your stones, you may be noticing spots of shine across the stone surfaces. In some advanced cases, you may also be observing that you are getting either inconsistent masa or coarser masa than you’d like for a table tortilla, no matter how tight the stones are set.

This is normal. First, let’s understand why it’s happening, and then let’s fix it together.

Why: Your stones are telling you that they are ready to be calibrated to your Molinito.

As perfect as any machine’s design is, whether a Vitamix or an iPhone, there are always the slightest of variations from machine to machine insofar as how their parts ultimately rest and settle in. Molinito is no exception. In Molinito’s case, this means that the stones will benefit from an additional fitting to your unique machine.

Further, the stones originate from a basalt mine in Puebla, Mexico, where they are individually carved to a general Molinito specification, but not to your newly broken-in Molinito. This, coupled with the fact that stones of this material are also different from each other (lava doesn’t cool the same in any one spot before it crystallized into rock!), means that there is additional variation that we can control through a quick calibration and resharpening.

How to fix it: You’ll need to run this silica sand through your Molinito. Not just any sand will do! Silver sand #20 is the exact type. You are welcome to buy the 100 lb bags they come in, or you can purchase 2.5 lb packages directly from us, here.

To use, you’ll want to moisten the sand to the consistency of wet masa. About 1 cup of water per 2.5lbs of sand will get you to the right consistency.

Next, run the wet sand through the auger into the stones while the machine is on. The stones should be pressed tightly together as if you were grinding table tortilla masa. Continue to tighten the stones as the sand moves through them. It will smell like burning, but this is normal. You are literally grinding down the face of your stones to a fresh face. Using a whole bag of sand (with water ratio) should do the trick. The outer half of the lines of the stone face should be erased with this step, leaving the cavity grooves as guides for re-carving fresh lines.

If you don’t want to calibrate your stones, you are also welcome to purchase new stones directly from Masienda.
