Quick answer
Sea Salt is evaporated sea salt from Coastal regions worldwide (Mediterranean, Atlantic, Pacific). Brighter and more briny than rock salt.
Key takeaways
- Sea Salt is evaporated sea salt from Coastal regions worldwide (Mediterranean, Atlantic, Pacific).
- Sea salt is produced by evaporating ocean water or saltwater from saline lakes.
- Sea salt composition reflects the mineral content of its source water.
- Sea salt is one of the most versatile salts in the kitchen.
Sea salt production dates back at least 8,000 years to coastal communities in China and the Mediterranean. The ancient Romans valued it so highly that soldiers were sometimes paid in salt, giving rise to the word 'salary' from the Latin 'salarium.'
Formation: Harvested continuously from current ocean water
How Sea Salt Is Made
Sea salt is produced by evaporating ocean water or saltwater from saline lakes. The most traditional method involves channeling seawater into shallow clay or stone pools along the coastline. Sun and wind gradually evaporate the water over weeks or months, leaving salt crystals behind. Workers rake the crystals into piles for collection. This process has remained largely unchanged for thousands of years in places like Guérande in France, Trapani in Sicily, and the salt pans of the Algarve in Portugal. Industrial sea salt production uses vacuum evaporation for faster, larger-scale output.
Mineral Profile
Sea salt composition reflects the mineral content of its source water. On average, sea salt is about 96-99% sodium chloride. The remaining 1-4% consists of minerals like magnesium, calcium, potassium, and sulfur. Specific mineral ratios vary by location. Mediterranean sea salt tends to be slightly different in mineral balance compared to Pacific or Atlantic varieties. These trace minerals affect both the color and taste of the final product.
Cooking with Sea Salt
Sea salt is one of the most versatile salts in the kitchen. Fine sea salt dissolves quickly and works well in baking, sauces, and soups. Coarse sea salt is ideal for brining meats and seasoning pasta water. Flaky sea salt varieties are prized as finishing salts, adding texture and visual appeal to dishes right before serving. The flavor of sea salt tends to be cleaner and brighter than mined rock salts, making it a go-to for seafood preparations and fresh salads.
Mineral Profile
Composition per 100g for sea salt. Values vary by harvest location and depth.
| Mineral | Content (g/100g) |
|---|---|
| sodium | 38 |
| chloride | 58.5 |
| calcium | 0.12 |
| potassium | 0.08 |
| magnesium | 0.05 |
| iron | 0.0001 |

Best Uses for Sea Salt
Recommended for
- Everyday cooking
- Finishing dishes
- Brining
- Seasoning blends
Not ideal for
- Situations requiring exact sodium measurements
- Long-term storage in humid climates without anti-caking agents
Chef's tip: Flaky sea salt like Maldon is best used as a finishing salt just before serving. The large flakes add crunch and bursts of salinity.
