Preserving Authentic Flavours: The Secret Behind Kaviari Preserves & Glass Jars

Kaviari's expertise extends far beyond caviar and fine delicatessen to encompass a refined collection of premium seafood preserves.

Each fish and seafood product is carefully prepared and sealed in glass jars to naturally extend its shelf life while preserving its original character. Sterilisation is carried out through carefully controlled thermal processes, whether using electric sterilisation, vacuum sealing through autoclaving or traditional bain-marie methods.

The preparations are then transferred into sterilised airtight jars. These containers protect the products from microorganisms, air and light, preserving both their freshness and the full intensity of their natural flavours.

What Foods Can Be Preserved in Glass Jars?

Airtight glass jars are ideal for preserving the freshness and flavour of exceptional products.

Kaviari offers a refined collection of delicacies including vintage sardines in olive oil, tuna belly, smoked sprats, sea urchin coral and Gravlax sauce — all carefully preserved to deliver an unparalleled tasting experience.

Complete Guide to Preparing & Sterilising Preserves

Creating seafood preserves is a delicate craft that combines tradition with precision to ensure optimal preservation. Each essential step plays a key role in maintaining freshness, texture and quality:

Product Selection

Choose exceptionally fresh ingredients — ideally organic and locally sourced — to ensure the highest quality preserves.

Preparation & Filling the Jars

Carefully clean each jar before filling it with the prepared ingredients, whether gently cooked or marinated.

Sterilisation

The sealed jars are then exposed to temperatures above 100°C. This heat treatment eliminates bacteria and other microorganisms while preserving the integrity of the product.

Sterilisation time must be adapted according to both the ingredients used and the size of the jar.

Storage

Once sterilised, the jars should be stored in a cool, dry place away from direct light to preserve their quality over time.

At Kaviari, this artisanal expertise is combined with rigorous control of hygiene and temperature conditions to preserve the freshness, delicate texture and authentic flavour of every product.

Tips for Optimal Preservation

Hygiene

Always work in a clean environment, whether in your kitchen or workshop.

Sterilisation

Sterilise jars and utensils beforehand to eliminate microorganisms and ensure optimal preservation.

Resting Time

Allow the jars to rest for a few minutes after sterilisation to ensure a perfectly airtight seal.

Labelling

Clearly indicate the contents and preparation date to manage your preserves efficiently. Repeated opening may reduce storage time.

Storage

Store jars in a cool, dry place away from direct light.

How to Enjoy & Elevate Your Preserves

For a refined aperitif, serve vintage sardines on warm blinis with a drizzle of extra virgin olive oil just before serving. Tuna belly pairs beautifully with fresh salads or gourmet toast.

Sea urchin coral is exceptional with creamy risotto or simply enjoyed on toasted bread. Crab meat, meanwhile, elevates elegant appetisers and delicate verrines.

For the perfect pairing, serve alongside a brut champagne or premium vodka to enhance the finesse and complexity of the flavours.
