According to the Guinness World Book of Records, the most expensive caviar, and indeed the world's most expensive food is 'Almas', from the Iranian Beluga fish - 1 kg (2 lb 3 oz) of this 'black gold' can be sold for £20,000 (then $34,500). Almas is produced from the eggs of a rare albino sturgeon between 60-100 years old, which swims in the southern Caspian Sea where there is apparently less pollution.
It's still only fish eggs, aka roe.)
