Caviar

Because the sturgeon eggs must be picked by hand, caviar is an acquired taste. It is also pricey. Sturgeon eggs, on the other hand, are almost entirely sourced from fish farms. The Caspian Sea's Osetra and Beluga caviars are among the most expensive. Iran's Golden Almas caviar is prized for its high price and delicate, velvety flavor.

Strottarga Bianco, on the other hand, is the most expensive caviar. This albino fish egg caviar is made from the Siberian Albino Sturgeon and is sprinkled with 22-carat gold.

Caviar has been used to treat depression in the past. Wouldn't it make you feel better if you were given caviar? It's not as strange as it sounds: new research suggests that high dosages of omega-3 fatty acids (caviar is abundant in omega-3s) can help with depression and bipolar disorder symptoms.

Strottarga Bianco can cost as much as $37,000 per teaspoon! In general, the paler the hue of the caviar, the more valuable it is.

Price: $34,500 a Kilogram
