The invention of the industrial bar
Four nineteenth-century innovations — the cocoa press, moulded eating chocolate, milk chocolate and the conche — turned an expensive drink into an inexpensive solid.
Chocolate as a solid bar is a nineteenth-century industrial product. Four developments made it possible in sequence.
The Dutch cocoa press, introduced in the 1820s, separated cocoa butter from the solids, which made cocoa powder possible and — more consequentially — made surplus cocoa butter available to add back into a mixture. Moulded eating chocolate followed in the 1840s, using that surplus butter to produce something that could be cast and eaten. Milk chocolate arrived in the 1870s once a workable method of combining milk with chocolate without spoilage was found. And conching, developed in Switzerland in the 1870s, produced the smooth texture that made the eating bar pleasant rather than merely possible.
The result within a few decades was a food that had been an elite drink for three centuries becoming an inexpensive everyday item.
