1, sea salt
Sea salt is a kind of edible salt, which is made by introducing seawater into the salt field and evaporating in the sun. Sea salt is mainly divided into crude salt, refined salt and flake salt. The production process of sea salt is complex, the production cycle is long, the production cost is high, and the taste and quality are good.
Step 2 pickle salt
Pickled salt is a kind of "slightly less accurate salt" and a kind of "dried sea salt formed after seawater evaporation". Generally speaking, these "sun-dried salt with larger particles" are more suitable for curing certain foods (vegetables or meat); Because of its large particles and slow dissolution, it is not suitable for daily cooking at home.
3. Low sodium rock salt
Rock salt, one of the salts produced on land. Once the seawater is changed into salt water on land due to geological movement, after a long-term evaporation process, these salt-containing substances crystallize to form a "rock-like seam". Low sodium rock salt reduces sodium ion intake and increases potassium ion intake, which is suitable for special people. This kind of salt has fine particles and is more suitable for daily cooking.
Types of salt
There were many kinds of salt in ancient times, including crimson snow, peach blossom, blue, purple and white. From the source, it can be divided into: sea salt is fried by sea brine, well salt is fried by well brine, alkali salt is fried by scraping alkaline earth, pool salt is dried by pool brine, and cliff salt is born between soil cliffs. Sea salt, well salt and alkali salt come from people, while pool salt and cliff salt come from heaven.
Modern Zhang Ming Shi records: "Xiezhou salt is made of geomantic omen, Ningxia salt scraped the ground, Huai and Zhejiang salt boiled, Sichuan and Yunnan salt mined, Fujian and Guangdong salt bittern, Huainan salt fried, Huaibei salt dried, Shandong salt fried."
