in 1828, coenraad johannes van houten made the first cocoa powder making machine in the netherlands. the press took apart the greasy cocoa butter from cacao seeds, leaving a chocolate powder behind. this powder — like the cocoa powder used now — was easier to stir into milk and water, and led to solid chocolate. by using cocoa powder and a little bit of cocoa butter, bar chocolate was then able to be made. the term "chocolate" then came to mean solid chocolate, instead of hot chocolate.
