Opening the tin should be the last step in preparation, not the first. The table can already be set, ice ready and spoons clean. The caviar can then stay refrigerated until everyone is ready to taste it. How you open it depends on the particular seal: inspect the package and follow its directions before touching the lid.

Start by identifying the tin and closure

Check the physical label, the condition of the container and any directions supplied with it. An editorial photograph cannot replace the instructions for that particular seal. If you have a compatible opener, such as the Cofré key, check how it fits before applying pressure; its appearance in a photograph does not mean it comes with the tin. If the opening point is unclear, stop and ask the Cofré team.

Avoid using a kitchen knife, a makeshift pointed tool or a sudden movement while holding the tin in your other hand. As well as damaging the rim or its contents, a slipping tool could cause injury. Set the tin on a stable surface and keep fingers and hands away from the path of the opener.

Prepare to serve while it remains closed

Wash your hands and prepare a clean surface. Have a cloth to steady the tin if needed, an ice-filled holder and clean mother-of-pearl spoons or another non-reactive utensil ready. If you will serve caviar with potato, bread or blinis, cook and arrange them first. The open tin should not have to wait for the kitchen to finish.

Open close to the first taste

Take the tin from the fridge, place it on a stable base and open it as directed for its seal and, if applicable, the compatible opener you have. Lift the lid carefully without touching the caviar with it. If the closure resists unexpectedly, do not increase the force or reach for a blade; ask the seller for help. Once open, bring the chilled tin to the table and offer small amounts with a clean utensil.

The first spoonful can be eaten on its own to recognise the texture and flavour. Afterwards, add a simple base if you like. Keep spoons that have touched other foods away from the caviar: setting out separate utensils is easier than dealing with an accidental mixture inside the tin.

What to do with any remaining caviar

Check the label for the specific storage conditions after opening. AESAN reminds us that opening packaged food may change both its usable period and its instructions. Keep the product as directed; do not assume a universal number of days. A careful opening ends when the caviar you did not serve returns to the cold conditions stated for it.
