Utensilios Prehispánicos: El molinillo. Cylindrical stick with a striated ball in the end, often around a ring. The grinder has evolved into a craft skimmer, but much more sophisticated. It is says his evolution goes hand in hand with the arrival of the monks and the preparation of hot chocolate with milk and sugar.
Authentic Mexican hot chocolate using molinillo and olla de barro ceramic pot. I wish you could see the molinillo. My mom has one, it's over 50 years old. We used to buy Pedro Lopez Chocolate but they've gone out of business.
