Black Caviar
The food of kings and one of the rarest gifts of the sea: glossy black sturgeon roe with a concentrated, distinctive taste of the sea. Caviar is almost free of net carbohydrate and the glycemic index does not apply; it is one of the richest sources of choline, omega-3 and phospholipids.

💡 Smart Nutritional Guidance
Consumption advice
A teaspoon is plenty to enjoy its nutritional value and luxurious flavour; eat it on crisp cucumber slices or a boiled egg rather than on refined white bread.
Best preparation methods
Serve it chilled straight away with mother-of-pearl or bone spoons, avoiding metal spoons, which can alter its pure flavour, and never heat it.
Important Nutritional Note
⚠️ Important clinical warning: caviar is very high in sodium, so people with high blood pressure should keep it moderate; pregnant women are advised to avoid raw or unpasteurised caviar because of the risk of Listeria bacteria.
