In order to achieve that velvety, restaurant-like finish on a lot of our sauces, aguas frescas, atoles, and even some moles, it is of the utmost importance to purchase a high-quality strainer with a double-fine mesh. In some cases, you may have to strain things twice to get them as smooth as possible. This is the best way to mimic the smoothness of sauces and atoles in Mexico that could only be achieved through local molinos, which are the neighborhood shops that offer fine stone-grinding services.
