What is the best thing to learn from the chef first?

Learn how to use all kinds of kitchen utensils scientifically in life;

1, avoid cooking mung beans in iron pot. Because mung bean contains tannin, it will produce black iron tannin when it meets iron at high temperature, which will make mung bean soup black and have a special smell, which not only affects appetite and taste, but also is harmful to human body.

2, avoid stainless steel or iron pot cooking Chinese medicine. Because traditional Chinese medicine contains a variety of alkaloids and biochemical substances, especially under heating conditions, it will have a variety of chemical reactions with stainless steel or iron, or make the drug ineffective, and even produce certain toxicity (when there are many complexes).

3. Avoid serving aluminum pot dishes. Aluminum pot is an outdated kitchen utensil. Because of its poor corrosion resistance, it will react with weak acid, weak alkali, salt and other substances to form special compounds, so dishes, wine, monosodium glutamate and so on should not be packed overnight in aluminum containers. And don't stir the eggs in the aluminum pot, because the egg white will turn gray when it meets aluminum and the yolk will turn green. Leftovers, soup, etc. Should not stay overnight in aluminum containers.

4. Avoid using ebony or smelly wooden cooking boards. Ubuntu contains odor and toxic substances. Cooking with it not only pollutes the dishes, but also easily causes vomiting, dizziness and abdominal pain. Therefore, the preferred wood for folk chopping boards is ginkgo, acacia, birch and willow.

5. Avoid using paint or carved bamboo chopsticks. The paint on chopsticks not only contains lead, benzene and other chemicals harmful to health, but also smells bad after heating, which affects appetite. Carved bamboo chopsticks look beautiful, because they hide evil and shelter evil, breed bacteria, are not easy to clean and easily cause diseases.

6, avoid using all kinds of porcelain to hold spices. Seasoning is best put in glassware. Colored porcelain contains lead, benzene and other pathogenic and carcinogenic substances. With the aging and decay of colored porcelain, radon in pattern pigments pollutes food and is harmful to human body.
