Everything you need to know about caviar….

What, exactly, is caviar?

Caviar is the eggs of the sturgeon (the Acipenseridae family).

Broadly, what does it taste of?

In 1000 Foods To Eat Before You Die, Mimi Sheraton describes it as

“those tiny, glistening, black-diamond beads that lie silky-soft on the tongue, exuding a mysterious essence of deep, dark sea salt with a vague patina of fishiness and the merest hint of earthiness…. In truth, what caviar tastes like is caviar.”

If you’re eating caviar in The States it will be saltier because borax, used in Europe as a preservative, is banned there, and salt is used instead.

Equally, caviar in vacuum-packed jars will have been pasteurised and additional salt added. The pasteurisation process involves cooking, which changes the texture of the delicate beads. Be very wary of anything which does not require refrigeration.

How should you keep it?

Keep it in the coldest part of your fridge (bottom back usually) ideally at temperatures of between -2 and +2ºC. No need to worry about it freezing due to the oil and salt content.

Once opened you should keep in the fridge and eat within a couple of days (once you have taken some out of the tin, some of the remaining eggs will break, and their oil seep around the other eggs…not ideal, also the eggs will react with the air).

How to check that your caviar hasn’t gone off

The eggs should be shiny and glistening… not wrinkly. They should smell of fresh sea air…no musty notes. There should be no liquid, just the perfect, round, unbroken eggs.

Is there a season for caviar?

Fish caught in cold waters has the most flavour. But it takes about six months for the roe to reach market. So, technically, the best time to buy caviar is in the spring or summer, although these days when all the fish is farmed it tends not to make that much difference.

When first harvested the eggs have a sort of elderly yoghurt taste (not too nice). Then salt and borax is added and the caviar begins to mature, in the same way that wine, cheese, and dry-aged beef does. Again, like a cheese, it’s turned regularly for up to 18 months, in the UK we like more delicately flavour, matured over three to six months. In France and the US they prefer a stronger flavoured caviar matured over a year.

The sustainability aspect

Post 1990s, after the collapse of the Soviet Union poaching and pollution pretty much destroyed sturgeon stocks in the Caspian sea. In 2006 the Convention on International Trade in Endangered Species recommended a complete ban on fishing for sturgeon in the Caspian and the export of caviar. The Caspian sea is bordered by Iran, Kazakhstan, Russia, Turkmenistan, and Azerbaijan. Since then the ban has been lifted, and specified amounts of caviar for each country to export have been set out.

But fishing wild sturgeon is certainly not the way to go, so farms have proliferated in the USA, France, Bulgaria, Britain, Italy, Israel, Saudi Arabia, Madagascar… and, most successfully in China which now accounts for some 60% of the world caviar market.

To find out more about how it is being ethically and sustainably produced in the UK, go to the KC Caviar website.

“In Moscow for an unrelated business meeting, Mark Zuckerberg has to pick up some cruelty-free caviar (Yotam! You really must rein it in) before a quick hop to the UK. He is hampered, though, by another mission – he must pass a test on applied ethics before boarding his flight.”

Janine Gibson, writing in The Financial Times about her fantasy dinner party

The different types

This is a natural product, and varies according to the fish, the season, the weather, and the processing. Like wine, given the right conditions an Oscietra caviar could be better than a poor quality beluga, in fact some connoisseurs prefer it anyway.

Below we give a general guide.

The three main types are:

Beluga, and beluga ‘000’ – the best?

There’s a general agreement (not unanimous, mind) that the best type comes from the Iranian-Russian controlled Caspian sea, from the endangered beluga sturgeon (huso huso). For a variety of reasons (environmental, political…) its import into the USA is banned. The eggs of the beluga are the largest, roundest, and most succulent, perhaps thanks to this omnivorous fish’s protein-rich diet.

The quality of these precious eggs is gauged by the colour, crystal-gray being the best, and allocated ‘000’ grade. The darker the shade, the fewer the zeros.

Osetra, ossetra, or oscietra

Oscietra is often a golden brown hue… but sometimes it’s a dirty ivory or green, It’s smaller and slightly softer than beluga, with a nutty, complex flavour, with a mellow aftertaste. It’s less creamy and more fishy tasting than beluga. Some connoisseurs prefer it. The oscietra sturgeon (Acipenser gueldenstaedtii) is omnivorous and also has a habit of escaping from predators by diving into the seabed – you are what you eat as they say, and the oscietra type can be rich and interesting.

Wendell Steavenson, writing in The Financial Times, describes it as follows:

“The ossetra had a softer texture but a more complex taste [than daurenki and baïka] of dark velvet sea under moonlight, and something else, curious and indefinable.”

Matthew Fort, writing in Esquire, reports:

“The tasting revealed how varied caviars could be, depending on breed of sturgeon, season and feed. If my memory is correct, Oz Clarke and I decided Chinese Oscietra from a spring-caught fish, was the most complex and satisfying of those on show.”

oscietra caviar
Oscietra caviar – because this was made in the summer (and extracted only about a month ago), the water wasn’t as clean, and it tasted a bit muddier. But, I thought, in a good way… like ruffled bed-hair is rather nice!


Sevruga caviar, from the sevruga sturgeon (Acipenser stellatus) is the least rare of the three, with smaller eggs than the beluga and the oscietra. It’s also graded by colour but it is usually jet-black. In terms of flavour it’s more in-your-face, more strongly sea-salty.

Then there are other types:


Sterlet caviar is rare, mostly only consumed, in the past, by royalty. It has small golden pearls.


Produces the second largest eggs after the beluga, taut and bursting – you almost have to resort to biting (cardinal sin). Eggs are glossy light to deep brown or golden in hue and come from the Huso Dauricus sturgeon, indigenous to the Amur River of China. Most is made in China. It has a sophisticated, strong, bright and fresh taste.

Baerii, baïka or Siberian

This type is from the Acipenser baerrii sturgeon. It’s silky, pure and refreshing… not so much of an aftertaste.

White sturgeon caviar

This type comes from the acipenser transmontanous (a close relative of the oscietra) from the eastern pacific ocean. Much comes from California, with some being farmed in Italy. I found it mild, creamy and buttery.

From the rare Japanese Acipenser schrenckii. Nutty and buttery, amber brown with a golden shimmer. Found in river basins in Russia and China.

Then there is caviar produced from hybrid fish – these fish are bred to grow to maturity much more quickly, and therefore reduce the cost of the caviar.


Caviar made from the eggs of a hybrid of the huso dauricus and Acipenser schrenckii. Larger, tauter eggs than the baerri, with a rich umami taste.


Caviar from a hybrid of the gueldenstaedtii with the Acipenser baerrii. Dark grey to ebony with intense hazelnut notes. At The Rivoli Bar in London’s Ritz Hotel they pair this caviar with Absolut Elyx vodka.

How to serve and eat it – less is more….sometimes

Lick it off your own flesh

Traditional purists insist that caviar is served best as simply as possible. Put a dab on the crevice between your thumb and index finger and lap it up appreciatively.

How much do you need?

Altogether, allow a minimum of 30g/1 oz per person…this is very miserly! You need at least three spoonfuls: the first to calibrate your taste buds; the second to develop a growing awareness of the scent of the sea…the soft texture on the tongue… the flavour; and the third to enjoy the whole pleasurable experience just for what it is. Do not, of course, try to bite the eggs – the whole point is for them to melt in the mouth…just as chocolate does! The reason why you need to really focus as you experience that second spoon is best described by Alexandre Petrossian, owner of the eponymous New York restaurant, who is quoted in the Serious Eats website saying,

“They say that a good caviar should have at least 15 different flavors in it,” he starts. “Each time you take a bite, you should taste something new. It should develop on your tongue and the aftertaste should linger for a very long time.”

Serve it at room temperature

Three or four minutes before serving take it out of the fridge and open the tin to allow it to breathe and reach room temperature.

What should you drink it with?

If you need a drink, then take a sip of cold vodka…or champagne.

Mark Addey, Managing Director of KC Caviar, says that Brian Copeland, Private Client Director of Remy Martin, suggested pairing it with his company’s legendary Louis XIII Cognac, and it was an astonishing success!

Alternatively, Cornel Ceapa, owner of Arcadia Sturgeon, suggests sake. You could try a Watari Bune Junmai Daiginjo.

Myths about using metal

Ensure the dab of caviar is transported onto your bare flesh on a non-metallic spoon…mother-of-pearl is traditional, but there’s always glass and plastic…

On the KC Caviar site we discovered that most metals (yes, including gold they say) react with caviar to change the taste…although it is possible to use plain old stainless steel.

What to eat with it

The less sensuous eater may allow himself plain, thin, unbuttered toast; or blini.

“Nignon is impatient, so we sit down and set about the blinis à la russe with ice-cold shots of vodka. Benjamin is very happy, as is Jennifer [Paterson, one of the Two Fat Ladies], who tried to eat caviar on her deathbed but didn’t manage it.”

Rowley Leigh, describing his fantasy dinner party in the FT.

The less purist eater may consider adding food without a strong taste, suggests quality caviar provider, Attilus… potatoes (mashed, new…all types), boiled eggs, or scallops are all candidates. Lemon, onion, and capers, on the other hand, can be overwhelming.

Creative pairing ideas

However, many chefs today are, thank heaven, inveterate experimentalists. Here are some caviar concepts currently on offer.

  • At Novikov, their own caviar (from a hybrid beluga and Siberian sturgeon) is served with Peking duck with its traditional train of pancakes, cucumber, spring onion and hoisin sauce.
  • At Bibendum, Claude Bosi serves it (Daurenki, this time; or, for those feeling flush, Oscietra) with finely diced smoked sturgeon mixed with jellied duck consommé and topped with spring onion cream.
  • Alex Dilling, at The Greenhouse, makes the same pairing with sturgeon, making a mousse of the fish and topping it with N25 caviar. The name of the roe comes from the latitude in the Yunnan Plateau in China where the fish are farmed. The whole is served on a bed of crab, ginger, and dill salad. This is just one of the intriguing caviar-laden dishes on offer. For other ideas, have a look at The Greenhouse menu.
  • André Garrett, at The Northall (the restaurant at The Corinthia Hotel) serves oscietra caviar on a brioche with egg yolk and venison tartare.
  • Joël Robuchon pairs it with cauliflower – the classic combination of the salty with the cruciferous (think bacon and Brussels sprouts). One of his concepts is to serve mashed potato with cauliflower cream and caviar, gelée de caviar à la crème de chou-fleur.
  • One of Wolfgang Puck’s signature dishes is a smoked salmon pizza, topped with crème fraîche, dill, and caviar.
  • Thomas Keller serves oysters topped with caviar on tapioca pearls in a vermouth sabayon. Marco Pierre White serves his with tagliatelle and oysters.
  • Heston Blumenthal has very successfully paired it with white chocolate. Both contain high levels of amines. There’s also the same salt-sweet thing going on which makes salted caramel so irresistible. If you’re sceptical try a small square of white chocolate tops with some high quality beluga…. As Blumenthal writes in The Guardian:

“…if you place the chocolate and caviar disc on the tongue, close your mouth and leave to melt. As the chocolate melts, the caviar flavour comes through gradually. You will be amazed by the pleasure of the changing flavours and sensations.”

I did try this, and I wasn’t unfortunately…chocolate too thick maybe….

caviar and white chocolate
Caviar and white chocolate: not quite as wonderful as we had hoped… but we didn’t make thin discs…
  • Lee Clarke, creating at The Haycock also pairs white chocolate and caviar. He sandwiches minced carrot between tuiles, and tops them with grated white chocolate and a dollop of caviar.
  • Jonny Lake, at Trivet, and once head chef at Blumenthal’s Fat Duck, serves sour cream and onion puffini, caviar and mirin sabayon. William Sitwell, writing in The Telegraph, describes enjoying a glass of ‘impeccable’ Assyrtiko from the Greek island of Santorini.

“This soothed me into a first course – more a canapé in terms of quantity – of a thing called a ‘sour cream and onion Puffini’. This is a sort of collapsible panini, in that it looks like a panini and it collapses as you pick it up. I did love it, though, with its salty bits of caviar, and a dip of frothy sabayon custard.”

  • Pairing it with eggs is a more run-of-the-mill combination. Frank Sinatra made scrambled eggs for Ava Gardner, and handed them to her topped with caviar.
  • At Ikoyi, a restaurant with a focus on sub-Saharan West Africa, chef Jeremy Chan serves Schrenckii caviar with aged beef and a plantain waffle.
  • At A Wong, Andrew Wong’s Cantonese restaurant, he serves Ossetra caviar with a sweet plum sauce in Peking duck pancakes.
  • At Da Terra, head chef Jing Wang serves caviar with rum ice cream
  • In pre-revolutionary Russia the Czar’s children breakfasted on banana and caviar, and Catherine the Great liked caviar omelette and vodka-laced tea after an exhausting night of love making.

  • At our caviar tasting with Kirill Siren, the toast was lightly spread with truffle butter. You could think that this was too much of a good thing…but it was perfect.
  • With crème fraîche and baked potatoes – to which Jackie Kennedy was partial
  • At Muse by Tom Aikens they offer Platinum caviar (see above) with onion in all its manifestations: custard, tea jelly, soup, roast oil, and the shell of a baked Roscoff onion!
  • And finally, you can get your inspiration from the poet, Sylivia Plath, who confesses:

“Under cover of the clinking of water goblets and silverware and bone china, I paved my plate with chicken slices. Then I covered the chicken slices with caviar thickly, as if I were spreading peanut butter on a piece of bread. Then I picked up the chicken slices in my fingers one by one, and rolled them so the caviar wouldn’t ooze off and ate them.”

Anything else we should know about it?

Lana Citron, in her fascinating book, Edible Pleasures, tells us

“Caviar is the perfect aphrodisiac, super high in zinc, vitamin A and Omega 3 fatty acids. It helps to increase blood flow, stimulate testosterone production and promote sperm development.”

So far, in spite of concerted effort (!) I have not been able to substantiate the aphrodisiac claim.

…. and finally….

“Is it OK to be pleased that Ronnie Wood’s four-year-old twins have inherited his taste for the high life? Ronnie is partial to toast and caviar for breakfast, and, apparently his daughters have developed a liking for ‘the black stuff’, so they all tuck in together. With taste buds like these, his girls will skip the whole Coco Pops phase and go straight to anchovies and plovers’ eggs, which will be a lot better for their health. It’s also good to know that being a rock star in old age isn’t all yoga and landscape gardening. If Ronnie’s tucking into beluga at the breakfast table, that’s rather reassuring.”
