Caviar has a reputation problem: it feels intimidating, so people either overspend or serve it wrong. A recent guide drawing on sommeliers, hotel beverage directors and caviar sellers on both sides of the Atlantic makes the case that getting it right at home is simpler than you'd think — and occasionally involves a Pringle.

Start with what you're buying. True caviar is sturgeon roe, and it comes in three main styles. Beluga is the rarest, with large eggs and a soft, creamy flavour. Osietra sits in the middle: medium eggs, rich and briny. Sevruga has smaller eggs, a punchier taste and a friendlier price. Salmon or trout roe often stands in as a budget alternative, but it isn't true caviar. According to Reid Lauber, senior food and beverage manager at the Lotte New York Palace, the biggest myth is that price equals quality — freshness and personal taste matter more than the sticker.

Provenance is worth a glance too. China, Russia and Italy have long dominated production, but newcomers are making noise: Exmoor Caviar is the UK's only producer and supplies Michelin-starred kitchens nationwide. Farmed caviar, once sneered at, is now the norm because wild sturgeon have been overfished. Reliable names include Paris's Petrossian (running since 1920), N25, Umai — which offers a caviar concierge service — and Fortnum & Mason's tasting set if you want to compare before committing.

Serving is where most people slip up, and the rules are strict. Keep the tin on ice: warm caviar spoils fast. Use a crystal bowl or coated metal to avoid taste transfer, and serve with mother-of-pearl spoons — they're not just decorative. The material doesn't oxidise on contact with salt, and it's gentle enough not to burst the fragile eggs. Metal spoons, by contrast, can taint the flavour.

As for pairings, the experts lean minimal: good bread, salted butter, a generous spoonful of caviar. But there's a fun counter-trend of dressing it down. James Stevenson of Brutes of Mayfair in London calls a sour cream Pringle with crème fraîche and chives "the perfect canapé," while New York's Coqodaq piles caviar onto a golden chicken nugget. On the drinks side, Stevenson pairs caviar with his bar's signature martini — the cold, clean cocktail cuts through the salt and richness, resetting your palate between bites. And if you're feeling adventurous, one chef swears by yoghurt gelato.

Why does this matter to travellers? Caviar tastings and martini-and-caviar pairings are increasingly on the menu at high-end hotel bars in London and New York, and knowing Beluga from Sevruga means you can order — or shop — with confidence instead of paying for a name. It also makes a genuinely impressive dinner-party move for the price of a decent bottle of wine.
