Salt is one of the most essential ingredients in every kitchen, but not all salts are the same. From everyday iodized salt to exotic Himalayan pink salt, each type has a unique composition, origin, and purpose.
In this detailed guide, we explore the chemical formula, health benefits, geographical origins, and price comparison of the most popular cooking salts used in India and worldwide.
What is Salt Made Of?
Most edible salts are primarily made of Sodium Chloride (NaCl). However, the difference between salts comes from:
- Mineral content
- Processing methods
- Natural impurities
- Crystal structure
