Bottarga Guide: Caviar vs Cured Roe, Uses and Cost

By Alex Beleaev | Beleaev Caviar & Gourmet, London

Bottarga is cured fish roe, but it is not sturgeon caviar. Beleaev's grey-mullet bottarga is salt-cured and air-dried into a firm amber piece that can be shaved or grated. Caviar is served as separate chilled pearls. Choose bottarga when the roe should season a dish; choose caviar when the individual pearls are the point of the tasting.

This guide explains the Italian mullet product, compares it with seven named Beleaev caviars and salmon roe, and shows how to budget without treating unlike packs as equivalent portions. Product descriptions and catalogue prices were checked on 12 October 2026. Flavour notes below come from the linked product listings; they are not the results of an independent tasting.

What is bottarga, and how is it made?

Bottarga is made by curing a whole roe sac rather than separating its eggs into a tin. Beleaev's product page describes grey-mullet roe, made in Italy in the Sardinian and Sicilian tradition. The pouch is handled to release air, packed in sea salt and slowly dried until the texture is firm and the flavour concentrated.

The resulting piece has a dense amber structure. A knife produces thin slices; a grater spreads small particles across a wider surface. That physical difference explains its role better than the nickname “Mediterranean caviar”. The nickname connects two roe products, but it should not hide the fish identity, drying process or way each is served.

The product listing describes a salty, nutty, savoury profile and calls bottarga the “truffle of the sea”. That is a culinary comparison to an ingredient used sparingly as a finishing accent. It does not mean bottarga contains truffle, has the texture of caviar, or comes from sturgeon.

Caviar vs bottarga: the useful differences

Neither form is a universal upgrade over the other. Grating bottarga into a dish uses the structure created by curing and drying. Grating or vigorously stirring caviar would remove much of the reason for buying whole pearls. Conversely, a thick mound of bottarga does not recreate the texture of a spoonful of caviar.

How each named caviar compares with bottarga

All seven sturgeon products below share the same basic contrast with bottarga: intact chilled pearls versus a cured roe piece. Their differences matter when choosing the chilled course. The final column gives the smallest currently available pack at this check, rather than an unavailable sampling option.

Imperial Gold is listed as a Huso dauricus × Acipenser schrenckii hybrid; do not call it pure Huso huso Beluga. Almaz Diamond is listed as albino Bester, Huso huso × Acipenser ruthenus; its pale colour is not proof of the wild origin or historical claims sometimes attached to “Almas”. For a purchase requiring detailed provenance, ask for the documentation for the named product and batch.

Salmon roe adds a third form to the comparison: separate large orange eggs from salmon. It differs from both the small sturgeon pearls and the dried mullet block. Choose it when orange colour and a juicy whole-egg topping suit the menu; use the received pack's handling instructions rather than borrowing those of another roe.

Choose by the dish and the recipient

• A plain spoon tasting: choose a named caviar, keep it chilled and allocate visible grams to each guest. Bottarga would create a different experience, even if served on the same spoon.
• A warm pasta or risotto: the linked bottarga is intended to be shaved or grated over the finished dish. Begin with restrained salt and adjust after the roe has been added.
• An egg or potato dish: choose caviar for distinct pearls placed on top after cooking; choose bottarga for a cured-roe seasoning spread across the plate.
• A two-course roe menu: keep the products in separate courses. A chilled caviar taste followed by a warm dish finished with bottarga makes the form and technique differences easier to notice.
• A gift: caviar suits someone intending a chilled tasting; bottarga suits a cook with a use for a whole cured piece. State the format clearly so a recipient expecting a tin of pearls is not surprised by a solid block.

These are serving choices, not a tested recipe or a claim that guests preferred one product. A strongly seasoned sauce, smoke, chilli or a second salty topping changes what can be noticed in either roe. Taste the complete base before adding more salt, lemon or dairy rather than treating any accompaniment as compulsory.

Pack price, price per gram and cost per plate

The checked bottarga pack was £19 for approximately 90g. Using the nominal 90g gives about £0.21 per gram. Royal Baeri's 20g tin was £27, or £1.35 per gram; Oscietra Royal's 20g tin was £38, or £1.90 per gram. These figures describe purchased weight, not equal serving value or a quality ranking.

For caviar, define the menu allocation first. Four guests receiving one 5g taste each need 20g. If all four receive a second 5g taste, the total is 40g: the first 20g tin cannot cover both rounds. One 50g Baeri tin, listed at £63 at this check, covers that 40g plan and leaves 10g; the whole pack purchase is still £63, not merely the value of the amount served. The 5g allocation is a planning example, not a guaranteed ideal dose for every dish.

For bottarga, weigh a trial portion used on your actual dish. Record the block's weight before and after grating, including any trimming, then multiply the measured use by the number of plates. Use the received net weight when exact yield matters. An approximately 90g pack does not support a guaranteed serving count, and the amount that balances one recipe need not balance another.

Compare the packs required, usable remainder and checkout total, including delivery or any chosen discount. Catalogue prices and available formats can change. Drying changes moisture and concentration, so a gram of bottarga and a gram of caviar should not automatically be treated as equivalent tastes.

How to slice or grate bottarga

A fine grating spreads the ingredient across pasta or risotto; a thin shaving leaves a more distinct piece on eggs or an antipasto plate. The current product page suggests olive oil and lemon with pasta or thin slices. Add gradually after the main cooking stage and taste the finished dish before increasing seasoning.

For repeatable service, use the same cut and base in your trial, record the amount added and check how evenly it reaches each plate. This establishes a dose for that preparation. It does not prove a universal rule about the strongest bottarga, the best wine match or how many meals every block will provide. Our bottarga buying and grating guide covers the cooking format in more detail.

Mullet bottarga vs tuna bottarga

Grey-mullet and tuna bottarga are made from different fish, so the fish should be named on the pack. Beleaev's linked product supplies a documented grey-mullet route. A tuna comparison also needs an exact product: named fish, curing and drying details, ingredients, net weight, current price and handling instructions.

Do not assume every tuna block is stronger or every mullet block is finer. Dryness, thickness of the cut, salt and the base dish can affect what is noticed. A matched comparison would use weighed amounts on separate portions of the same lightly seasoned base, then record the observations for those batches. This guide reports no such completed comparison and gives no tuna price or storage promise.

Storage, allergens and ordering

The current bottarga product page says to keep the sealed pack in a cool, dry place. After opening, it says to wrap the piece and refrigerate, with best use within 30 days. Follow the received label, dates and any more specific instructions. The listing identifies fish as an allergen; check the complete pack declaration and the other ingredients on the plate.

Keep caviar chilled under the named tin's instructions. Do not transfer bottarga's opened-life wording to caviar or salmon roe, and do not assume all cured roe has identical storage rules. A menu should be planned around safe use of the whole purchased pack, including any remainder.

For delivery, check the postcode, available date and final charges at checkout and read the current shipping policy. Curing does not establish a universal delivery or temperature guarantee. Choose the roe whose format matches your dish, then confirm the exact pack and receiving arrangements.

Frequently asked questions

Is bottarga the same as caviar?

No. Sturgeon caviar is sold as separate salted eggs, kept chilled. The linked grey-mullet bottarga is a salt-cured, air-dried roe sac, sold as a firm piece to slice or grate. Both are fish roe, but they have different forms and serving roles.

Can bottarga replace caviar on a blini?

It can create a different cured-roe bite, but it will not reproduce whole caviar pearls. Use a thin shaving and taste the base before adding salt. If the menu promises a caviar tasting, use the named sturgeon caviar rather than presenting bottarga as an equivalent.

Is bottarga cheaper than caviar?

The checked Beleaev bottarga listing was £19 for approximately 90g on 12 October 2026, compared with £27 for a 20g Royal Baeri tin. These are unlike packs. Compare the amount actually used per plate, the packs required and the checkout total; a lower nominal price per gram does not measure quality.

How should I use bottarga?

The linked product page suggests thin shavings or gratings over finished pasta, risotto or eggs, or thin slices as an antipasto. Add gradually and taste before increasing salt. This guide does not specify a fixed gram dose or guarantee a number of servings from one block.

How should I store the linked bottarga?

The current Beleaev product page says to store the sealed pack in a cool, dry place; after opening, wrap it and refrigerate, with best use within 30 days. Follow the received label and its dates where more specific. These instructions do not establish an opened-life rule for caviar or salmon roe.

Is mullet bottarga better than tuna bottarga?

There is no universal winner. The fish, curing, moisture, cut and dose all affect the comparison. This guide documents Beleaev's grey-mullet product, not a matched test against a named tuna bottarga; check the exact tuna product before making a flavour, storage or value comparison.
