What cooking knowledge is essential before learning to cook? You won't regret it after reading the guarantee. I often cook at home recently, and I know something. It only involves family knowledge, not professional cooking. Say as much as you think, and make up for it later.

Slice pork: Slicing pork is the opposite of cutting beef, because the meat quality of pork is delicate and weak. If it is cross-cut, it will become messy and not shredded after frying. Therefore, the pork should be cut obliquely, so that it will not be stuffed or broken. Cut beef: beef has many tendons and is mixed along the grain of meat fiber. If you don't carefully observe the cutting, many tendons will remain in the shredded pork as a whole. Dishes fried with shredded pork like this are hard to chew and look "old", so shredded beef should be cross-cut.

when blanching vegetables, adding some salt and oil to the water can make the vegetables more colorful and keep their nutrition.

Generally speaking, you know about seasonings: salt, soy sauce, light soy sauce, chicken essence, steamed fish soy sauce, white sugar, oil consumption, etc. If you want to learn how to cook well, you must also know the taste of seasonings, otherwise, if you fry a vegetable, you will also put soy sauce, oil consumption and other seasonings, and the cooked food will definitely not be delicious!

try to buy less semi-finished ingredients. Most of the semi-finished dishes in supermarkets and food markets are filled with a lot of sodium bicarbonate, tender meat powder and monosodium glutamate, which is not delicious, unhealthy and uneconomical.

The chopping block must be classified into raw food and cooked food, otherwise there will be a risk of cross-infection of bacteria. If possible, it is best to separate meat, fish, vegetables and cooked food.

when cooking, the oil temperature should not be too high, and 8% heat is the best. Because when the oil temperature is above 2℃, it will produce a kind of harmful gas called "acrolein", which is the main component of lampblack, and it will also cause oil to produce a large number of peroxides that are extremely carcinogenic. Don't worry about washing the pan after frying vegetables, let it cool for a while and then wash it, otherwise the hot pan will suddenly get cold and will soon break without coating.

Tofu is soaked in boiling water for more than 1 minutes before it is put into the pot, so that the bittern smell can be removed. The tofu made in this way is delicious and sweet.

Brown sugar stored for a long time will become hard. Don't worry. Sprinkle some water on it, cover it with a wet tissue, and then microwave it for 3 seconds, and it will become soft.

put the pork on the chopping board, cut the meat at an oblique angle of 45 degrees, and be careful not to cut the meat, then turn it over in situ and cut it obliquely. After cutting 45 degrees from the front to the back, cut the knife straight at 9 degrees and cut both sides. This cutting method allows you to chop pork easily and cut it directly into the end.

when cooking soup, if you mainly eat meat, add boiling water, so that the meat is more tender. If you mainly drink soup, add cold water to make the soup fresher (but don't add water halfway).

when stir-frying vegetables, you must order boiled water for some water. If it is cold, the color of the vegetables will turn black and look bad.
