Our community held a lecture on salt before, which mentioned this matter. High-quality salt is relatively white in color, uniform in particles, free from caking, impurities and peculiar smell. Generally speaking, find some big brands of salt and go to a regular supermarket to buy it. The quality of salt is guaranteed. I usually buy seaweed iodized salt on snowy days. "Snow Day" is a well-known trademark in China. I trust this brand of salt more, and it really didn't let me down. The cooking is very delicious. You can think about it.
