Blue salt

Blue salt is a special type of salt that has been mixed with a blue substance, often a mineral like prussian blue, which gives it its distinctive color. Unlike regular white table salt, blue salt isn’t just for flavor—it’s designed to serve specific practical purposes, especially in preventing clumping and adding certain health benefits in some cases.

Why people use it

People use blue salt primarily to keep moisture away and to make salt flow freely, just like how adding a few grains of rice to a salt shaker can stop it from getting clogged. The blue coloring also makes it easy to see and measure, which is helpful in cooking or industrial settings. In some regions, blue salt is also valued for containing trace minerals that can be beneficial, similar to how sea salt offers more natural elements compared to highly processed table salt.

Basic examples

In the kitchen, blue salt can be used in salt shakers to prevent lumps, especially in humid climates. It ensures that when you’re seasoning your food, the salt comes out smoothly without needing to tap or shake the container hard.
In food preservation, such as making pickles or curing meats, blue salt helps maintain consistency and prevents caking, which is important for even flavor distribution.
Some people also use it in bath salts or spa products for its aesthetic appeal and potential skin benefits, much like how Epsom salt is used for relaxation.
