1, the time of stewing chicken legs can't be generalized, which has a certain relationship with the type of chicken and the size of chicken legs. If the legs of broilers are basically soft and rotten about 20 minutes after the soup is boiled, it will take at least half an hour or more for free-range chickens, especially some older chickens, to taste.
2, to identify whether the chicken leg is cooked, you can use chopsticks to tie it. If chopsticks can't be inserted into the chicken leg, or blood comes out when they are inserted, it means that the chicken leg is not cooked and needs to be stewed for a while.
