Caviar is processed, salted, non-fertilized sturgeon roe marketed as a luxury food. According to the Food and Agriculture Organization, caviar is a product made from salt-cured fish-eggs of the Acipenseridae family. The roe can be "fresh" (non-pasteurized) or pasteurized, with pasteurization reducing its culinary and economic value.

Traditionally the term caviar refers only to roe from wild sturgeon in the Caspian and Black Sea (Beluga, Ossetra and Sevruga caviars). Depending on the country, caviar may also be used to describe the roe of other fish such as salmon, steelhead, trout, lumpfish, whitefish, and other species of sturgeon.

Based on flavor, size, consistency and colour, prices for caviar range from $8,000-$16,000 per kg^{[citation needed]}. Caviar is marketed worldwide as a delicacy and is eaten as a garnish or a spread.

According to the United Nations' Food and Agriculture Organization, roe from any fish not belonging to the Acipenseriformes species (including Acipenseridae, or sturgeon stricto sensu, and Polyodontidae or paddlefish) are not caviar, but "substitutes of caviar." This position is also adopted by the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the World Wide Fund for Nature, the United States Customs Service, and the Republic of France.

Gordon James Ramsay, OBE (born 8 November 1966) is a British chef, television personality and restaurateur. He has been awarded 13 Michelin stars in total and currently holds 12.

Ramsay is known for presenting TV programmes about competitive cookery and food, such as the British series Hell's Kitchen, The F Word, Ramsay's Best Restaurant, and Ramsay's Kitchen Nightmares, along with the American versions of Hell's Kitchen, Kitchen Nightmares, and MasterChef.

Gordon Ramsay was born in Johnstone, Renfrewshire, Scotland, and raised in Stratford-upon-Avon, Warwickshire, England from the age of 5. Ramsay is the second of four children; he has an older sister, Diane, a younger brother, Ronnie, and a younger sister, Yvonne. Ramsay's father Gordon (died 1997) was, at various times, a swimming pool manager, a welder, and a shopkeeper; his mother, Helen Cosgrove, and Yvonne have been nurses. Ramsay has described his early life as "hopelessly itinerant", as his family moved constantly due to the aspirations and failures of his father, who was violent. In 1976, they finally settled in Stratford-upon-Avon where he grew up in the Bishopton area of the town. In past public interviews, Ramsay has declined to describe his father as an alcoholic; however, his autobiography, Humble Pie, describes his early life as being marked by abuse and neglect from this "hard-drinking womaniser". At the age of 16, Ramsay moved out of the family house into a flat in Banbury.
