La Madeline au Truffe created by Fritz Knipschildt is the most extravagant and most expensive chocolate in the world. It sells for around $2,600 (£2,020) per pound, or $250 (£194) per piece. This sweet indulgence is hand-crafted using a dark chocolate ganache and a French Perigord truffle. The ganache is made using 71% single bean Ecuadorian dark chocolate mixed with fresh cream that has been infused for 24 hours with the flavor of vanilla beans and pure Italian truffle oil.
The ganache is then shaped around the French Perigord truffle (the truffle alone costs up to $1,000 per pound/454 grams), then dipped in 71% Ecuadorian dark chocolate and rolled in cocoa powder. The result is pure extravagance lying on a bed of sugar pearls in a silver box tied with a ribbon.
