1, bone soup should be boiled while it is hot, and it must be kept in a pot at a high temperature. Don't always open the lid, it will make the hot air lose and affect the temperature in the pot.

2. Don't add water frequently. Because bone soup takes a long time to boil, many people will frequently open the lid and add water during the boiling process. It is suggested that the fire can be properly adjusted to medium fire to reduce water loss. If it is necessary to add water, you should boil the water before adding it. Remember not to add cold water directly.

3. If you want to make the color of bone soup white, don't add salt in the boiling process. You need to wait until the boiling is complete, and then add salt when you want to drink soup.

Tips for making bone soup:

1, add a spoonful of vinegar when cooking bone soup, which can dissolve phosphorus and calcium in bones and preserve vitamins in the soup.

2. Before cooking the big bone soup, soak the big bone in water and wash away the floating foam. If the floating foam in the soup is not removed, the final soup color will be affected.

It's better to fry the big bones in hot oil in advance. Generally, stir-fry onion and ginger, add bones and stir-fry, and then cook wine.

4. Never add cold water halfway, lest the temperature of the soup suddenly drop, which will lead to the rapid solidification and denaturation of protein and fat, and affect the nutrition and taste.

5, don't put salt too early, salt will make the water contained in the meat run out quickly, and it will also accelerate the solidification of protein and affect the umami taste of the soup.
