Origin of ground soy sauce: China has cultivated soybeans for more than 5,000 years. In this process, soybeans are processed into various products, and there will be a lot of dregs in this production process. Later, people thought it was too wasteful to throw away the dross, so they decided to add seasonings such as sugar and salt to the dross for further processing, which produced ground soy sauce.
The difference between ground soy sauce and other soy sauces is just like soy sauce. Soy products such as flour soy sauce can see the shape of soybeans, but ground soy sauce is made of dregs, so the shapeless paste on the appearance is slightly heavier than other soy sauces.
