At first glance, caviar as a concept seems fairly straightforward: fish eggs served with a tiny spoon. But there’s so much more to it. Few ingredients have inspired quite the same mythology – or mystique – as these small, lustrous pearls. Spanning millennia, this is a dish once so common as to be almost banal, turned rare and deeply ritualised.
Caviar is defined, quite strictly, as the salt-cured, unfertilised eggs of sturgeon. That definition matters. While the word is often applied loosely – salmon caviar, trout caviar, even lumpfish caviar – none of these are technically correct. They are roe, and while roe can be delicious, true caviar only comes from sturgeon. This distinction is what gives caviar its status and its price. The eggs are gently separated, lightly salted and preserved to maintain their structure, flavour and freshness. The best examples are firm, clean-tasting and balanced, never aggressively salty.
Ancient Persians are believed to have been the first to salt sturgeon roe, valuing it for strength and nourishment. The word itself likely comes from the Persian khav-yar, loosely translating to “cake of power”. Greek writers, including Aristotle, recorded sturgeon roe being served at banquets as early as the fourth century BC. Along the Caspian Sea and the Volga River, fishermen ate caviar as a practical food source, not a luxury. Its tendency to spoil without refrigeration made it difficult to transport, and over time, that perishability contributed to its exclusivity. It was Russia, and particularly the Russian Tsars, who pushed caviar firmly into the realm of luxury. Certain species, such as the sterlet, became highly prized for their delicate flavour and pale colour. By the Middle Ages, sturgeon had achieved near-royal status across Europe. In 1324 England, King Edward II declared sturgeon a “royal fish”, a legal concept that still exists today. By the nineteenth century, growing demand across Europe led to intensive harvesting in the Caspian region, laying the groundwork for the overfishing that would follow.
The twentieth century marked a turning point. Caviar became widely fashionable, appearing in high-end restaurants and, somewhat ironically, as free bar snacks in parts of the United States to encourage drinking. Demand quickly outpaced supply. Pollution, dam construction and illegal poaching pushed wild sturgeon stocks into severe decline. Today, all legal caviar comes from farmed sturgeon. Sustainability is no longer a marketing angle, but a necessity.
Caviar is best served simply. Temperature is critical. Caviar should be kept extremely cold, but never frozen, and served over ice to maintain its texture. Metal should be avoided entirely, as it can taint the flavour. Traditional serving vessels and spoons are made from mother of pearl, bone or shell for this reason. While champagne is a popular pairing, very dry styles work best. Vodka remains the most traditional match, valued for its ability to cleanse the palate between bites.
Today, caviar occupies a different space than it once did. At Belthazar, it is not about excess or spectacle, but about craftsmanship, restraint and respect for the product. From ancient riverbanks to modern sustainable farms, caviar’s journey mirrors a shift towards thoughtful indulgence – where provenance matters and simplicity is.
