The most expensive chocolate in the world is CHOCOPOLOGIE
It cost $2600 per pounds..Its creator is Knipschildt…
Founded by Fritz Knipschildt, a chef who got his culinary education in Denmark, in 1999, Knischildt creates one of the world’s tastiest chocolates. Its costliest on-piece chocolate is a $250 dark chocolate truffle with French black truffle within it (in picture). This special truffle, available only on a pre-order basis, is mainly composed of 70% Valhrona cacao blended into a creamy ganache with truffle oil. The truffle is made with extremely precise bare hands and finally dusted with cocoa powder.
