Oyster sauce is a condiment made by concentrating the juice of oyster after cooking or directly hydrolyzing oyster meat, adding sugar, salt, starch or modified starch, supplemented by other ingredients and food additives. Oyster sauce was first invented in Guangdong with a history of more than 200 years. Popular in Guangdong, Fujian and other places.

In recent years, with the mutual penetration of eating habits and the improvement of income level in various parts of China, oyster sauce has developed rapidly outside Guangdong, and its taste and function are gradually becoming familiar to consumers all over the country. Oyster sauce has a uniform posture, moderate viscosity, reddish brown to brown, bright and shiny, and has the function of polishing and stimulating appetite.

Compared with soy sauce, oyster sauce is more delicious. Besides glutamic acid, ribonucleic acid is also the main flavor of oyster sauce. At the same time, oyster sauce is rich in seafood and fish flavor, forming a major feature of oyster sauce. Oyster sauce is not only a good condiment, but also has rich nutritional value. The main nutrients in oyster sauce are amino acids, zinc and taurine.

Usage of oyster sauce:

1, oyster sauce needs heating. Oyster sauce can't be put directly in dishes such as salt and chicken essence, especially when making cold dishes. The correct way is to heat it in a pot, which can stimulate the umami flavor of oyster sauce and make the cold dishes taste better.

2. The heating time of oyster sauce should not be too long. Because oyster sauce is an oily substance, if it is heated for too long, it may destroy the tissue components in its body and make its taste less good. Therefore, we must grasp the time when heating oyster sauce.

3. Don't eat with heavy seasoning. Although oyster sauce is delicious, it is very light, which is best reflected in cooking. If you eat it with a strong seasoning, you won't feel it at all.

4, braised, sweet and sour dishes do not put oyster sauce. Whether it's braised or sweet and sour, sugar should be added. In principle, oyster sauce should not be used with sweet and sour. Sugar itself has a refreshing effect, and adding oyster sauce is equivalent to refreshing for the second time. There is a lot of sodium glutamate (the ingredient of monosodium glutamate) in oyster sauce, so it will be bitter if you use it too much.
