The Primary Names: Sel Gris and Grey Salt
For those wondering what is Celtic salt also called, the most common and accurate answer is its French name, sel gris, which translates directly to “grey salt”. This name is a nod to its characteristic color, which comes from the clay of the salt pans where it is harvested. The term “Celtic” was popularized as a brand name in the 1970s, but the traditional harvesting method and the resulting product have been known as sel gris for centuries.
The Origins of Celtic Salt and Its Unique Properties
Celtic salt has a rich history rooted in the coastal regions of Brittany, France, particularly around the town of Guérande. Here, the salt is produced using centuries-old techniques designed to maintain the salt’s natural integrity. This artisanal approach is the foundation of its distinct characteristics, including its color, moisture, and flavor.
Traditional Harvesting Methods
The Celtic method of salt harvesting relies on a natural process of solar evaporation and wind. Seawater is channeled into a series of clay-lined salt pans, or marshes. As the water evaporates, salt crystals form. Paludiers, or salt harvesters, use wooden tools to rake the salt from the bottom of these pans. This hands-on process, untouched by metal, is believed to preserve the salt's natural qualities.
The Role of Clay
The unique, grayish color and moist texture of Celtic salt are directly influenced by the clay found in the marshes. As the salt crystals form and are hand-raked, they absorb trace minerals from the clay. This is a key difference between Celtic salt and highly refined salts, which are stripped of all impurities and trace minerals during processing. The mineral-rich clay imparts over 80 trace minerals, including magnesium, calcium, and potassium, which contribute to the salt's distinct flavor profile and perceived health benefits.
Celtic Salt vs. Other Popular Salts
While many people are familiar with table salt and Himalayan pink salt, Celtic salt offers a unique set of qualities. Here is a comparison of these three common salts:
| Feature | Celtic Salt (Sel Gris) | Table Salt | Himalayan Pink Salt |
|---|---|---|---|
| Origin | Coastal regions of France (Brittany) | Various sources, often inland salt mines | Khewra Salt Mine in Pakistan |
| Processing | Minimally processed, hand-harvested | Heavily refined, bleached, and dried | Mined from ancient sea beds |
| Mineral Content | Rich in trace minerals from clay (magnesium, calcium, potassium) | Stripped of most minerals during refining | Contains trace minerals, including iron oxide (giving it its color) |
| Color | Grayish with a moist, coarse texture | Pure white, fine grain | Pink or reddish-pink, dry texture |
| Flavor | Complex, briny flavor | Purely salty taste | Subtly salty with a mineral edge |
Culinary Uses and Benefits
Celtic salt is a favorite among chefs and home cooks for its ability to enhance the natural flavors of food. Its moistness means it does not dissolve as quickly as table salt, making it an excellent finishing salt for a pleasant crunch and burst of flavor.
How to Use Celtic Salt in the Kitchen:
- Finishing Salt: Sprinkle coarse crystals over roasted vegetables, grilled meats, or salads just before serving.
- Brines and Marinades: Use it in brines for poultry or in marinades for meat to impart a deeper, more complex flavor.
- Baking: A touch of Celtic salt can be used in baked goods, like salted caramel desserts or rustic bread, for a savory-sweet contrast.
- Flavor Enhancement: Its nuanced flavor can elevate the taste of simple dishes like homemade chips or freshly shucked oysters.
Conclusion: The Many Names of a Mineral-Rich Salt
In summary, Celtic salt is also called sel gris or grey salt, referencing its French origin and distinctive color derived from clay. This hand-harvested, unrefined sea salt is more than just a seasoning; its traditional production process ensures a rich mineral profile and a moist texture that adds both depth of flavor and unique characteristics to a wide range of culinary applications. Choosing Celtic salt over heavily processed table salt offers a more natural and flavorful option for enhancing your meals.
