What do you mean you're sick of chocolate? Well it's hardly our fault if you ingested a coop's-worth of eggs over the weekend is it? Buck up and educate yourself.
This visual guide from Robert Shaw provides a snack-sized history to the humble chocolate bar, documenting the foodstuff's early development from medicinal purposes to the modern billion pound industry.
Useful ammunition for the next pub quiz, the guide reveals which European nation gets through the most bars, how far one cocoa bean goes and the company behind the largest chocolate empire. Here's hoping the info lasts you longer than the average KitKat.
