Sauerkraut, any sauerkraut is ok, Northeast China, Sichuan and Guangdong. I recommend Sichuan sauerkraut. Soaked at home, bought in a bag outside, whatever you want.

Needless to say, trotters can be bought everywhere.

First: I think this hot pot is cooked directly. Can we serve now? So, wash the pig's feet first, soak them in cold water for an hour to remove the fishy smell and blood.

Second: cut the onion, ginger and garlic into pieces, chop the sauerkraut, put the oil in the pot, add the onion, ginger and garlic after heating, add the sauerkraut, stir-fry the fragrance, and then pour the water into the pot. It doesn't matter if there is more water. When the water boils, it becomes sauerkraut soup, and the pig's feet are put. I suggest you kill the pig's feet and try them.

Third: after boiling, simmer until the trotters are edible, salt and chicken essence. okay
