Fleur de Sel (Sea Salt): what every chef needs to know
Hard to run a kitchen without Fleur de sel — the thin, crunchy layer of sea salt crystals that forms on the surface of salt pans in summer and is harvested by hand. The best-known origins are Guérande (Brittany) and the Camargue (Provence). Fleur de sel has a larger, flaky crystal structure than regular sea salt, resulting in a different texture and a milder, more complex flavour from a higher mineral content. Fleur de sel is exclusively a finishing salt: never cook with it, always add only at the last moment on the plate. The crunchy texture lost through heating is the distinguishing characteristic. Price: €15–40 per kg, but per portion you use 0.3–0.5 grams: the cost per portion is negligible compared to its perceived value.

Frequently asked questions about Fleur de Sel (Sea Salt)
What is the difference between fleur de sel and regular sea salt?
Regular sea salt is produced by evaporation and has small, uniform crystals. Fleur de sel floats as a thin flake on the surface and is harvested by hand: it has larger, irregular flakes with a different mouthfeel. Fleur de sel also has a slightly lower sodium content due to the presence of magnesium and potassium salts preserved during the production process.
Why should you not put fleur de sel in the cooking water?
Heating dissolves the crystal structure so the distinguishing crunch effect disappears. Furthermore, fleur de sel is 30–50 times more expensive than cooking salt: the financial argument is as strong as the culinary one. Use regular coarse sea salt or kosher salt for cooking and blanching water, and reserve fleur de sel strictly as a finishing salt.

Allergen information: Limitations
The allergen information on this page relates to the ingredient as such. The actual allergen composition of your purchase may differ due to:
- Varying suppliers, production facilities or growing regions;
- Cross-contact during production, transport or storage ("may contain");
- Changed product formulations not yet reflected in public sources;

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
