Who invented the conching process used to give chocolate a smoother texture in 1879?

Rodolphe Lindt invented the conching process used to give chocolate a smoother texture in 1879.

Lindt developed the process in Bern, Switzerland, after acquiring a chocolate factory and experimenting with machinery. His conche repeatedly kneaded and warmed chocolate, improving its texture and helping distribute cocoa butter evenly.

Before conching, chocolate could be coarse and gritty because ground cocoa particles were not fully dispersed. The process also helped reduce harsh flavours and moisture, producing chocolate that melted more smoothly in the mouth.

Conching is still used in chocolate manufacture, although modern equipment and recipes vary. It should not be confused with tempering: conching develops texture and flavour, while tempering controls cocoa-butter crystals so finished chocolate sets with a shine and a clean snap.
