Key Differences

Sea Salt and Rock Salt are two diverse types of salt used for various purposes. Sea Salt is sourced directly from the evaporation of seawater. It retains some trace minerals from the ocean, giving it a unique taste and texture. Conversely, Rock Salt is derived from ancient salt deposits found underground. As these deposits are remnants of evaporated seas from prehistoric times, Rock Salt is essentially aged Sea Salt. However, Rock Salt often contains impurities due to its underground origins, sometimes making it unsuitable for direct consumption.
