Chocolate Bar

100 grams of happiness in a foil wrapper/Food & Drinks

A standard chocolate bar weighs about 100 grams, is roughly 20 cm long, and packs about 2.3 million joules (550 calories) of energy. Chocolate was consumed as a bitter drink by the Aztecs for centuries before Europeans added sugar and turned it into the confection we know today. The melting point of cocoa butter (about 34°C) is just below human body temperature, which is why chocolate melts so satisfyingly on the tongue.
