Pork trotters jelly is a delicious snack that is often cooked. The general practice is 1 kg trotters with 3 kg of water, and the water is added at one time. After the water is boiled, simmer slowly, turn off the fire when the trotters are soft and rotten, and let them cool to a frozen state. There is no requirement for a few kilograms of water to make pig's trotters jelly, as long as the water does not pass the pig's trotters.
