Storing salt in the refrigerator is not a common practice and is generally not necessary. Salt is a mineral that is naturally stable and does not spoil or deteriorate over time when stored properly. Most people store salt in a cool, dry place, such as a pantry or a kitchen cabinet, at room temperature.
However, there might be a few reasons why some people store salt in the refrigerator:
Humid Climate: If you live in an area with high humidity, moisture can affect salt and cause it to clump or become lumpy. Storing salt in the refrigerator can help prevent moisture absorption and keep the salt dry.
Preventing Clumping: If salt is exposed to air and humidity, it can clump together, making it challenging to use. Refrigerating salt can help prevent clumping, but it's worth noting that high-quality table salt usually contains anti-caking agents to prevent this issue.
Personal Preference: Some people prefer the sensation of using cold or chilled salt in their dishes, especially if they add salt to certain foods just before serving. The chilled salt might offer a different taste experience.
While refrigerating salt can be done for the reasons mentioned above, it is generally unnecessary for common table salt and other types of salt like kosher salt or sea salt. If you choose to store salt in the refrigerator, make sure to use a tightly sealed container to avoid any potential absorption of odors from the fridge.
For most households, storing salt in a dry, cool pantry or kitchen cabinet at room temperature is perfectly adequate and convenient.
