Yes, storing salt with desiccant packets is a good idea, especially in humid environments, as it helps prevent the salt from clumping and absorbing moisture.
Salt, particularly table salt, is hygroscopic, meaning it readily absorbs moisture from the air. This absorbed moisture can cause the salt crystals to stick together, forming clumps that are difficult to break apart. Desiccant packets, typically containing silica gel or other moisture-absorbing materials, work by drawing moisture away from the surrounding environment. By placing desiccant packets in the same container as your salt, you create a drier environment that inhibits moisture absorption by the salt. This helps to keep the salt free-flowing and prevents clumping. The effectiveness of this method depends on the type of desiccant used, the size of the container, and the humidity level of the environment. For best results, use food-grade desiccant packets and ensure the container is properly sealed.
If you don't have desiccant packets, a few grains of uncooked rice can also help absorb moisture in your salt shaker or container. Just be sure to replace the rice periodically.
