Document Summary

30% men and 38% women preferred chocolate to sex. Melting point: 36c - we like the texture of chocolate. Theobroma cacao - theo : god; = food of the gods. Aztecs would use coco drinks to satisfy gods - very difficult to dissolve. Cocoa = very bitter; aztecs called it zocoatl for bitter. Cocoa also used as currency - spaniard believed cocoa had aphrodisiac properties - also thought would increase libido. It is believed that what is really enjoyed is the melting in the mouth: became popular in europe as drinks, so add sugar, vanilla, cinnamon so chocolate was drunk, not eaten. Cocoa flower converted to puds - grows on branches. Forastero, criollo, trinitero: criollo: split it open, surrounded by white. Let it ferment - sugar gets converted to alcohol acetic acid esters (adds flavor) Ivory coast: top producer (then guana, and then indonesia) by far: child labor (bitter chocolate - carol off) One fermentation process done, drying, then roasting.
