Many families have this problem ~ it's not worthwhile to buy a bottle of oyster sauce just to cook a dish! Now I'll teach you something simple ~ Oyster sauce is mainly used to improve the umami taste of dishes ~ Then let's consider other fresh-keeping things! For example, delicious soy sauce ~ seafood soy sauce ~ soy sauce ~ soy sauce! It's really troublesome ~ just use soy sauce! You should be cooking with juice, right? You pour a little water directly into the pot ~ add soy sauce! Appropriate to add a little chicken essence ~ monosodium glutamate ~ feel delicious enough! Boil ~ add the starch (water starch, that is, add water to dry starch) and it feels thick ~ put a little salad oil ~ OK~ fake oyster sauce ~ Success! If you cook lettuce in oyster sauce ~ cook the lettuce in clear water and put it on the plate! Just pour (fake oyster sauce) on it and it's OK!
