In addition, some people put the above ingredients together and cook them for a long time, then turn off the heat if they are sticky. This cooking method is unscientific. First of all, garlic will lose its function if cooked for a long time. Second, honey will lose some nutrients at high temperature; Third, vitamin C in lemon and apple vinegar will be lost in large quantities; Fourth, there are food additives in apple vinegar, which will change at high temperature for a long time, which is not good for your health, so don't cook at high temperature for a long time, just boil it. The purpose of cooking is sterilization and disinfection, which is conducive to preservation. Honey is used for seasoning, and it is anti-virus. It doesn't need to be boiled, so it can be put later.
