Which is better: large grain salt or fine salt?

Large grain salt is just ordinary salt. Ordinary salt includes coarse salt and solar refined salt. Coarse salt refers to sea or lake salt produced in the original salt fields. Solar refined salt, referring to China's southern coastal salt areas, is made according to high temperatures and frequent rainfall. They use new brine, thin evaporation, short-term crystallization, and regular movement of brine and salt residue to produce fine salt with uniform grains.Refined salt, also known as processed salt, is made from refined brine using underground natural brine or brine obtained by rock salt water extraction. It removes soluble impurities through chemical methods, clarifies it, and then undergoes evaporation, crystallization, dehydration, drying, and screening. Salt mines produce refined salt using underground natural brine or brine from rock salt water extraction. In the selected refined salt, after adding appropriate anti-caking agents and mixing evenly, it becomes refined salt. Refined salt contains no impurities.
