When cooking, salt should be put in when the pot is almost cooked, which makes it taste better and more scientific. It is not good to put it too early. And monosodium glutamate must be put in the pot immediately, which is poisonous! Never put monosodium glutamate in scrambled eggs.
Also, under normal circumstances, soy sauce is definitely not used for frying vegetables. Pay attention to color, aroma and taste when frying vegetables. You can watch some cooking programs, in which writing tips is very useful. There is no need to copy recipes mechanically. I've tried, some recipes look good, and they taste really pleasing!
Cutting vegetables is also learned, such as cutting meat, pork and beef are different, one is cut along the grain, the other is cut against the grain.
Also, when frying fish, the skin of fish is easy to stick to the pot, so when you cook the pot, clean the pot with ginger before putting oil, and put less salt in the oil. Put the fish when the oil is hot. Don't turn it over in a hurry. You can gently shake the pan so that the fried fish looks good.
Fire fighting, this is hard to say, I think slowly, and I will feel if I do too much slowly.
