Step-by-step explanation:
Malú's abuela had cacao beans that were chipped off into coffee to sweeten it. The indigenous people of Mesoamerica, including the Olmecs, Mayans, Aztecs, and Toltecs, cultivated cacao beans and used them to make a drink called xocolatl. They would grind the beans into a paste, thin it with water, and add sweeteners, such as honey. The drink became popular in Europe and was eventually introduced to Spain by the Spaniards in the New World.
