2. Many people put onions, ginger, peppers, aniseed, cooking wine and other ingredients in order to make bone soup taste better, but you said you didn't need so many ingredients to make hot pot soup. I suggest you just add a little pepper and ginger (but I don't like ginger, you can try it according to your own preference).
Besides, I will give you some advice.
Before cooking, you should soak the bones in cold water for more than 2 hours, and pay attention to changing the water halfway, so that there will be no flocculent floating objects (blood left on the bones solidified) after cooking, which will make the soup look clear and greatly improve the delicious taste of the soup.
To make the bone soup delicious and nutritious, we should first put the bone in a cold water pot, gradually raise the temperature and boil it, and then simmer it with slow fire to loosen the bone tissue and gradually depolymerize and dissolve the protein and fat in the bone.
Note that in the process of boiling bone soup, don't add cold water halfway, otherwise the temperature of the soup will suddenly drop, which will not only affect the nutritional components of the soup, but also affect the freshness and fragrance of the soup.
