Sea Salt vs. Rock Salt: What's the Difference?
Sea salt is obtained through evaporating seawater; rock salt is mined from underground salt deposits.
Sea salt is harvested by evaporating seawater, capturing the salt that remains. Conversely, rock salt is extracted from large underground deposits which were formed from ancient seas and lakes.
Due to their differing sources, sea salt typically contains a variety of minerals from the ocean, giving it a complex flavor. Rock salt, being from ancient deposits, often has fewer minerals, resulting in a more straightforward salty taste.
The texture differs between the two as well; sea salt can be found in both fine and coarse varieties, while rock salt usually has large, chunky crystals, making it popular for uses like ice cream making and de-icing roads.
While sea salt is often praised for its slightly briny flavor and is commonly used in gourmet cooking and as a finishing salt, rock salt is generally less expensive and is used in industrial applications, cooking, and household chores.
The coloration of sea salt can vary based on its mineral content and source, ranging from white to pink to gray. In contrast, rock salt is typically white, though impurities can sometimes give it different hues.
