1. How to cook is a healthy practice?
1. Heat the pot first, then pour the oil, and then immediately pour the ingredients into the pot, so that the oil temperature will not be too high and the temperature will be below 240 degrees. But if the oil temperature is too high, it will cause a series of decomposition of oil, and the grade right released by polymerization is equally harmful. Volatile components will produce carcinogenic macromolecular rings and also produce oil fume.
2. When the raw materials are put into warm oil, there is an instant buffer after heating, and the chef can quickly use this moment. Weaving or slipping the raw materials will gradually denature the protein on the surface of the raw materials, which is convenient for stretching and spreading, so that the raw materials are fully and evenly heated, and the ingredients are good in taste and beautiful in shape.
The heat at the bottom of the pot is very high. When the grease is cold, after the raw material is put into the oil, with the increase of the oil temperature, it can generate a thrust to make the raw material float up quickly, so as to prevent the raw material from breaking and not sticking to the pot.
Second, how to master the cooking temperature?
Stir-frying usually takes a short time. Generally, strong fire is used for cooking, but the fire time should not be too long. Stir-fry with medium heat oil first, and then put the materials in slow fire, which takes a long time to soak and fry until they are cooked. Generally, stir-fry with strong fire first, then with slow fire, and the fire lasts longer. Ingredients with old texture and big body are suitable for long-term and low-fire cooking, while ingredients with tender texture and small shape are suitable for short-term and high-fire cooking.
3. What are the advantages and disadvantages of ordering takeout compared with cooking at home?
1. It's more expensive to order takeout. The cleaning and preparation of ingredients may not be clean. If you cook it yourself, the oil and materials used are more secure and healthier to eat.
2. You don't have to go out to buy or wait for delivery. If you cook it yourself, you have to buy ingredients. It's a bit troublesome to go home and tidy up the ingredients.
