Making flaky sea salt involves a process of evaporation and recrystallization. While there are many variations, the fundamental steps remain consistent.
The Process of Making Flaky Sea Salt
-
Seawater Collection: Begin by collecting clean seawater. The ideal location would minimize contamination from pollutants.
-
Evaporation: The seawater is then placed in a shallow container or basin with a large surface area. This allows for efficient evaporation, driven by sunlight or heat. Traditional methods involve large, open-air evaporation ponds, while smaller-scale production can use shallow pans, slow cookers, or even a dedicated dehydrator. The slower the evaporation, the larger and flakier the salt crystals tend to be. [Reference: Many sources, including Alphafoodie, Grit Magazine, and Reddit's r/foraging, discuss the fundamental evaporation process.]
-
Crystallization: As the water evaporates, the dissolved salt begins to crystallize. The rate of evaporation significantly impacts the crystal structure. [Reference: Alphafoodie mentions this aspect in the context of recrystallization after initial dissolving and dehydration.] Slow evaporation promotes the formation of larger, flaky crystals, as opposed to fast evaporation which yields smaller grains. [Reference: Margaret Schlegel's blog post highlights the importance of this slow process for achieving flaky salt.]
-
Harvesting: Once the majority of the water has evaporated, leaving behind salt crystals, the flakes are carefully harvested. Traditional methods for flaky sea salt often involve skimming the surface during the evaporation process, collecting the delicate crystals as they form. [Reference: Wellspent Market’s article on fleur de sel illustrates this skimming technique.]
-
Drying (Optional): The harvested salt may require further drying to remove any remaining moisture. [Reference: Alphafoodie mentions the use of a dehydrator or other low-heat methods for this step, as well as allowing air drying.]
Types of Flaky Sea Salt
The process can produce different types of flaky sea salt, depending on the method employed. For example, fleur de sel is a delicate, hand-harvested variety skimmed from the surface of salt pans during the evaporation process. Other methods may produce coarser flakes.
Practical Considerations
- Water Purity: The quality of the seawater directly influences the final product. Contaminated seawater will result in impure salt.
- Evaporation Rate: Controlling the evaporation rate is crucial for producing desired crystal size and shape.
- Harvesting Technique: Gentle harvesting methods are essential to preserve the delicate structure of the salt flakes.
