White caviar from the albino beluga sturgeon that lives in the Caspian Sea is the most sophisticated and expensive food in the world. Although this fish usually lives for more than a 100 years, there are very few of the albino variety left in the wild since the lack of melanin is a genetic disorder that only affects a few members of the species. As the sturgeons get older, their eggs are more elegant, smooth, aromatic and delicious with a spongier texture. The most expensive is the exclusive variety Almas (Russian for “diamond”) sold in a 24-carat gold metal container. Price? $25,000 per kilo!
